Why Do We Think UFOs Are Alien?

What Are They?

The question is not whether Unidentified Flying Objects are “real.” By their very definition, they are; an object, seen in the sky, that is unidentified, is a “UFO.” The U.S. government, after decades of official dismissal, now openly investigates what it calls Unidentified Anomalous Phenomena, or UAP, acknowledging their existence with a new, destigmatized acronym. Pilots, radar operators, and satellites record data on objects that do not behave like known aircraft or natural phenomena. The data, in a small but persistent number of cases, is very real.

The central question – the one that has captivated and defined the phenomenon for over 75 years – is what they are.

For a significant portion of the public, and for a growing number of credible insiders, the answer has coalesced around a single, extraordinary explanation: they are alien. They are intelligently controlled craft from a non-human intelligence, originating from somewhere other than Earth.

This immediate leap from “unidentified” to “extraterrestrial” is the single most fascinating aspect of the phenomenon. It’s a conclusion that is not necessarily supported by the balance of evidence, yet it has become the default cultural assumption. The term “UFO” itself has become so completely synonymous with “alien spacecraft” that military and scientific bodies were forced to invent a new term, “UAP,” just to have a conversation free from the cultural baggage.

This article does not seek to prove or disprove that hypothesis. Instead, it seeks to answer the deeper question: Why do we think this? What is the complex machinery of history, media, government secrecy, and human psychology that forged this immediate and enduring link?

The answer is not a single event, but a complex, self-reinforcing story – a modern mythos – built from several distinct pillars: a foundational pair of sightings in 1947, a cultural furnace of Cold War anxiety, a powerful feedback loop of pop culture, the paradoxical effect of government secrecy, a persistent kernel of genuinely anomalous data, and the significant, timeless human quest for meaning in the cosmos.

From Unidentified Object to Alien Craft

The idea that we are being visited by beings from other worlds did not begin in 1947. It is a concept as old as the first person to look at the stars and wonder if someone was looking back. H.G. Wells, in 1895, had already written the definitive alien invasion story with The War of the Worlds. Pulp science fiction magazines of the 1920s and 30s were filled with tales of Martians and space-faring heroes. But these were, unequivocally, fiction.

The shift from speculative fiction to contemporary, non-fictional “news” happened with astonishing speed in the summer of 1947. It was a moment of cultural transformation, the dawn of the Atomic Age and the Cold War. Humanity had unlocked the power of the atom, developed rocket technology, and was staring into a new era of technological wonder and existential terror. The world was primed for a new kind of story.

A New Lexicon: From Flying Saucer to UAP

Before we can trace the origin of the belief, we must first understand the language we use to describe it. For most of the 20th century, the operative term was “UFO,” which stands for “Unidentified Flying Object.” This term was technically coined by the U.S. Air Force to replace the more sensational “flying saucer.” It was intended to be a neutral, bureaucratic catch-all for any aerial object – a weather balloon, a misidentified planet, a secret aircraft, or anything else – that a witness could not immediately identify.

Over the next half-century, this technical neutrality was completely eroded. Through a cultural process of association, “UFO” came to mean one thing and one thing only in the public mind: an alien spaceship. The term became so loaded, so synonymous with extraterrestrial visitors, that it became a “giggle factor” word. Pilots, military officials, and scientists were reluctant to use it, fearing for their careers and reputations. The word itself had become a barrier to serious investigation.

This contamination of the original term is the entire phenomenon in miniature. To escape this stigma, official bodies in the 21st century – particularly the U.S. Department of Defense – made a deliberate linguistic pivot. They adopted the term “UAP,” which stands for “Unidentified Aerial Phenomena” or, in its more recent and broader form, “Unidentified Anomalous Phenomena.”

This new term was a bureaucratic reset button. It was chosen specifically to “differentiate the sightings from the extraterrestrial association” and to destigmatize the act of reporting. The very existence of the word “UAP” is a testament to the power of the alien hypothesis; the belief that “UFOs are alien” became so culturally dominant that the government was forced to invent a new, “clean” vocabulary just to do its job.

The 1947 Spark: Kenneth Arnold and a New Word

The event that lit the fuse of this modern phenomenon occurred on June 24, 1947. The witness was, by all accounts, ideal. Kenneth Arnold was not a fringe figure; he was a 32-year-old successful businessman, a respected community member, and a highly experienced pilot from Boise, Idaho, with thousands of hours in the air.

While flying his private plane near Mount Rainier in Washington, searching for a missing military transport, Arnold saw a flash of bright light. He then observed a chain of nine, bright, crescent-shaped objects flying in formation. They were moving at an incredible speed, weaving along the Cascade Mountains.

What made Arnold’s report impossible to dismiss was his professional calculation of their speed. He timed their movement between Mount Rainier and Mount Adams, a distance he knew well. His conservative estimate put their speed at over 1,200 miles per hour; his higher estimate was closer to 1,700 mph. In 1947, this was an unthinkable speed. The sound barrier had not yet been officially broken by a manned aircraft. This was three times faster than any known jet.

When he landed, Arnold reported what he saw. He described the objects’ shape as a “crescent” or “like a pie plate.” But he described their motion as erratic, “like a saucer skipping on water.” A newspaper reporter, in a moment of historic misinterpretation, conflated the two descriptions. The headlines the next day did not report “crescent-shaped objects”; they reported “flying saucers.”

This media misprint was, perhaps, the most important accident in the history of the subject. “Flying saucer” was a visual, catchy, and instantly memorable brand. It gave a distinct shape and name to the unknown. The term exploded across the globe, and within weeks, hundreds of other people began reporting “flying saucers” of their own. Arnold’s credible sighting, combined with the media’s sticky new terminology, created a template. People now knew what to look for.

The “explanation vacuum” created by Arnold’s report – it wasn’t our planes, so what was it? – was immediately filled by this new archetype. The “flying saucer” was born.

The Roswell Incident: A Crash and a Cover Story

If Kenneth Arnold’s sighting provided the name and shape of the phenomenon, the second event of that summer provided its mythology. Just weeks later, in early July 1947, something crashed on a remote ranch near Roswell, New Mexico.

A rancher named W.W. “Mac” Brazel discovered a large field of strange debris. He described it as including tinfoil-like material that couldn’t be crumpled, lightweight balsa-like sticks that couldn’t be broken, and strange bits of “tape.” He reported it to the local sheriff, who in turn called the Roswell Army Air Field (RAAF), home to the 509th Bombardment Group – the only atomic bomb squadron in the world.

What happened next is the single most important reason the “government cover-up” narrative exists. On July 8, 1947, the public information officer at the RAAF, Walter Haut, issued an official press release to the media. The headline was unambiguous: “RAAF Captures Flying Saucer on Ranch in Roswell Region.”

The story was an international sensation. The “flying disc” phenomenon that Arnold had just reported was not just a sighting; it was real, physical, and in the possession of the U.S. military. The Army itself had confirmed it.

The sensation lasted only a few hours. The military’s reaction was swift and decisive. High-ranking officers flew in immediately, collected the material, and flew it to Fort Worth, Texas. General Roger Ramey, the head of the Eighth Air Force, hastily called a press conference. He announced that the entire thing had been a mistake. The “flying disc” was, he claimed, nothing more than a common high-altitude weather balloon. He had his weather officer pose for photos, holding up the tattered remains of a balloon and a radar target, which looked nothing like the debris Brazel had described.

The media, facing a four-star general, obediently retracted the story. The Roswell “flying disc” became the Roswell “weather balloon,” a footnote and a punchline.

But the story didn’t die; it went dormant. The government had, demonstrably, lied. The initial, sensational press release (“flying disc”) was quickly and clumsily replaced by a mundane, dismissive one (“weather balloon”). This created a significant cognitive dissonance. Why the initial excitement from the intelligence officer who first saw the debris? Why the massive, high-level military response for a simple balloon?

Decades later, in the 1990s, the Air Force declassified the real story, admitting that the “weather balloon” explanation was also a cover story. The debris was, in fact, from Project Mogul, a top-secret (and then-unacknowledged) program that used long trains of high-altitude balloons to carry sensitive acoustic equipment, in an attempt to listen for the sound waves of Soviet nuclear tests. The secrecy around this program was why the military had to shut the “flying disc” story down so quickly and completely.

But by the time this truth came out, it was too late. The “alien” narrative had already taken root. Starting in the late 1970s, retired military officers who had been at Roswell, like Jesse Marcel, began to speak out, claiming the “weather balloon” story was a lie. They were, of course, right. But in the absence of the (still classified) Mogul explanation, they speculated that the debris must have been extraterrestrial.

This is the bedrock of the entire alien conspiracy. It exists because the government demonstrably lied. The military’s own actions – the sensational first press release, followed by a clumsy and false retraction – created an information vacuum that begged to be filled by a conspiracy. The cover-up wasn’t of aliens, but the cover-up itself (of Project Mogul) is what convinced an entire generation that it must have been aliens.

The Extraterrestrial Hypothesis Emerges

In the fertile soil of 1947, the Extraterrestrial Hypothesis (ETH) – the theory that UFOs are intelligently controlled “extra-terrestrial vehicles” (ETVs) – formally took root.

The idea was not just a public fancy. Arnold himself had publicly raised the possibility. More important, the government’s first official investigation, Project Sign (launched in 1948), became internally divided on the question. While the official stance of the Air Force, led by Chief of Staff General Hoyt Vandenberg, was that the sightings were a combination of misidentified aircraft and natural phenomena (and, privately, a fear of advanced Soviet technology), a minority faction of analysts and engineers within Project Sign came to a different conclusion.

These researchers, after analyzing the flight characteristics of the best reports, concluded that the objects were indeed real, mechanical, and displayed performance far beyond any known terrestrial capability. They drafted a top-secret “Estimate of the Situation” which concluded that the ETH was the most likely explanation for the high-quality sightings. This estimate was famously rejected by General Vandenberg, who cited a lack of physical evidence, and the report was ordered destroyed.

This internal, classified debate from 1948 shows that from the very beginning of the official investigation, the “alien” explanation was being seriously considered by trained government analysts. It was not just a public delusion; it was a contested hypothesis within the deep recesses of the military establishment itself.

A Mirror to Our Anxieties: The Cold War and the Alien

The events of 1947 did not happen in a vacuum. They were a spark that landed in a tinderbox of global anxiety. The “flying saucer” phenomenon became the perfect screen upon which a terrified world could project its deepest, most modern fears.

Invaders from Mars, Invaders from Moscow

The end of World War II did not bring peace. It brought the Atomic Age and the immediate start of the Cold War. For the first time in human history, mankind possessed the technology for its own total annihilation. This was a new, abstract, and overwhelming terror.

This existential dread was paired with a more conventional, but no less potent, political paranoia: the “Red Scare” and the fear of the Soviet Union. This was the era of McCarthyism, of a faceless, infiltrative “other” that could be “hidden among us in plain sight.”

The “alien” narrative provided a perfect, symbolic container for both of these anxieties.

The fear of “aliens among us,” which became a staple of 1950s and 60s comic books and B-movies, was a direct and obvious reflection of the fear of communist spies. The “enemy in our midst” was a powerful cultural trope, and the alien “infiltrator” was a more fantastic, and perhaps more manageable, version of the Soviet “sleeper agent.”

Simultaneously, the “alien invasion” trope, resurrected from H.G. Wells, became a potent metaphor for nuclear war. Hollywood films presented visions of potential threats from the sky. Would the visitors be benevolent, like in The Day the Earth Stood Still (1951), coming to warn humanity about its self-destructive path? Or would they be ruthless destroyers, as in Earth vs. the Flying Saucers (1956)?

This central question – “Are they peaceful or will they destroy us?” – was the exact same question Americans were asking about the Soviet Union. The UFO, a technologically superior and mysterious object, became a projection of our terrestrial fears onto the cosmos. It was, in some ways, an easier narrative to process than the more abstract, self-inflicted horror of mutually assured destruction.

Hollywood Builds the Myth

Science fiction, which had once been a niche genre, now had a direct line to the mainstream. Hollywood and the growing television industry seized upon the new “flying saucer” phenomenon and the accompanying Cold War anxieties, creating a powerful “feedback loop” that would come to define the public perception of aliens.

Here is how the loop worked:

1. A real sighting occurs: A pilot or civilian reports a strange light or object (like the Kenneth Arnold sighting).
2. Media reports the sighting: The news uses the new “flying saucer” terminology.
3. Hollywood adapts the sighting: A studio produces a film, like The Thing from Another World (1951) or Invasion of the Body Snatchers (1956), that borrows from the real reports but adds a narrative of horror, infiltration, or invasion.
4. A “collective shorthand” is created: These films provide the public with a rich, detailed, and visuallibrary for what aliens, their ships, and their intentions should look like.
5. A new sighting occurs: A person sees an ambiguous stimulus – a light, a cloud, a sensor glitch.
6. The brain interprets the sighting: Instead of interpreting the ambiguity as an “omen” (as they might have in 1850) or a “weather balloon,” the witness’s brain, steeped in this new pop-culture library, interprets it as a flying saucer with hostile aliens.

This feedback loop is a key reason why we think UFOs are alien. Pop culture became a “fantasy” realm that co-opted real, unexplained events and provided a detailed, pre-packaged narrative for them. Before 1947, a strange light was an “unexplained phenomenon.” After the 1950s, it was a “flying saucer” carrying “little green men” who were here to either save us or conquer us. The alien hypothesis was, in effect, a new, technological folklore for the Atomic Age.

The Media Takes It Seriously: The 1952 Life Article

For five years, the “flying saucer” debate was largely confined to newspapers, pulp magazines, and B-movies. It was sensational, but not yet “serious.” That all changed on April 7, 1952.

Life Magazine, arguably the most dominant, mainstream, and trusted publication in middle-class America, published a major article with a shocking title: “Have We Visitors From Space?”

This was not a short, dismissive piece like one Life had run in 1947. This was a long, deeply-researched, and “strongly sympathetic” article that treated the Extraterrestrial Hypothesis as a serious, objective possibility. The piece was written by H.B. Darrach Jr. and Robert Ginna, who had been given remarkable access to Air Force officials.

The article detailed the best cases from the Air Force’s files, including the “Lubbock Lights” in Texas and the mysterious “Green Fireballs” being seen over sensitive military installations in New Mexico. It even included illustrations based on pilot testimony.

Most important, the article was openly critical of the government’s official dismissals. It criticized Project Blue Book’s investigations as a “sedative to public controversy” rather than a genuine, serious inquiry. It quoted high-ranking (though anonymous) intelligence officials who admitted they did think the objects were extraterrestrial.

The impact of this article cannot be overstated. By appearing in Life, a “safe,” establishment publication that just weeks earlier had President Truman on its cover, the ETH was instantly legitimized. It gave “social permission” to millions of Americans to consider the impossible. It moved the “alien” hypothesis from the margins to the very center of American cultural conversation.

The article is widely credited with helping to trigger the massive “UFO flap” of 1952, a wave of sightings that culminated just months later in the famous “Washington, D.C. flap,” where “flying saucers” were repeatedly tracked on radar over the White House and the U.S. Capitol. The Life article had made the alien hypothesis not just believable, but expected.

The Government’s Shadow: Secrecy, Projects, and Public Distrust

The government’s response to the UFO phenomenon is, paradoxically, the most powerful engine for the alien hypothesis. It was not the government’s belief in aliens, but its secrecy about its own activities, that convinced the public of a cover-up. The alien conspiracy theory is the unintended, and perhaps inevitable, consequence of a national security state operating in the shadows.

Project Blue Book and the 701 “Unknowns”

From 1947 to 1969, the U.S. Air Force ran a series of public-facing investigations into UFOs. After Project Sign (which was divided) and the short-lived Project Grudge (which was designed to debunk), the longest and most famous study was Project Blue Book, which ran from 1952 until its termination in December 1969.

Headquartered at Wright-Patterson Air Force Base in Ohio, Project Blue Book collected and investigated a total of 12,618 UFO reports. In 1969, following the recommendation of a government-funded scientific study (the Condon Report), the Air Force shut the project down.

The official conclusions of Project Blue Book were definitive and absolute:

1. No UFO reported, investigated, and evaluated by the Air Force was ever an indication of a threat to our national security.
2. There was no evidence submitted to or discovered by the Air Force that sightings categorized as “unidentified” represented technological developments or principles “beyond the range of modern scientific knowledge.”
3. There was no evidence indicating that sightings categorized as “unidentified” were “extraterrestrial vehicles.”

The case, it seemed, was closed. The official answer was “no aliens.”

But buried in the project’s own final statistics was a single, explosive data point that would render the official conclusions moot for an entire community of believers: 701 of the 12,618 cases remained, officially, “unidentified.”

This was a catastrophic public relations failure. The Air Force’s own multi-decade, official study admitted that nearly 6% of the cases it investigated were inexplicable.

For a skeptic, this 6% is simply a lack of data – cases where the information was too poor to make a judgment. But for a proponent of the ETH, this 6% was the “signal in the noise.” It was the proof. The government’s own data, they argued, showed that a real, anomalous phenomenon existed. The official conclusion (“no aliens”) had to be a lie, a cover-up designed to hide the truth about the 701 “real” ones.

The government’s attempt at transparency (releasing the numbers) backfired completely, providing the very “evidence” that the phenomenon was real and that the official “no aliens” conclusion was a public-facing lie.

The Real Secrets: Spy Planes in the Sun

The great irony at the heart of the “cover-up” is that the government was hiding something. It just wasn’t aliens. It was hiding its own, extraordinarily advanced, top-secret aircraft.

In the 1950s and 60s, at the height of Project Blue Book, there was a massive spike in UFO reports, particularly from credible witnesses like commercial airline pilots. Decades later, a declassified CIA report revealed the astonishing truth: more than half of all UFO reports from this period were, in fact, sightings of two specific American spy planes: the Lockheed U-2 and the SR-71 (also known as the A-12 or “Oxcart”).

These planes were black projects, the most valuable national secrets of the Cold War. They flew at altitudes and speeds that were, to the public, scientific impossibilities.

The U-2, for example, flew at altitudes above 60,000 feet. Commercial airliners of the day flew between 10,000 and 20,000 feet, and military bombers topped out below 40,000. No one believed manned flight was possible at 60,000 feet.

This created the perfect conditions for a “UFO” sighting. An airline pilot, flying from east to west at sunset, would be in darkness at 20,000 feet. But the U-2, 40,000 feet above him, would still be in the direct sunlight. Its silver wings would catch and reflect the sun, appearing to the pilot below as a “fiery object” or a brilliant, impossibly high light.

What happened next is the step-by-step creation of a conspiracy theory:

1. The Sighting: A credible airline pilot, a trained observer, sees a real, advanced, high-altitude object that he knows is not a plane, a star, or a balloon.
2. The Report: He reports this “UFO” to the Air Force’s Project Blue Book, as he is required to do.
3. The “Investigation”: The Blue Book investigators, knowing full well about the classified U-2 program, would call their contacts at the CIA. The CIA would confirm that a U-2 was in the area at that time.
4. The Lie: The Blue Book officer, legally bound to protect the U-2’s existence, would then lie to the pilot. They would issue a false “debunking,” telling the pilot he had misidentified Venus, seen a “sprite,” or was fooled by a “temperature inversion.”
5. The Conclusion: The pilot knows he didn’t see Venus. He knows he is a professional. He knows, with 100% certainty, that the United States Air Force is lying to him.
6. The “Why”: Why would they lie? He doesn’t know about the U-2. But he does know about the “flying saucers” from Life magazine. He concludes that the government is lying to hide the real truth: it was an alien craft.

This cycle repeated hundreds of times. The government was actively using the “UFO” phenomenon as a cover story for its own advanced technology. The necessary secrecy of the national security state was the primary engine driving the alien conspiracy.

The Feedback Loop: How Secrecy Breeds Conspiracy

This created a “UFO taboo.” Pilots and other military personnel learned very quickly that reporting a UAP was a career-ending move. They were ridiculed, told they were “crazy,” and “disparaged” by the very institutions that were causing many of the sightings. This stigma pushed the entire topic out of “serious” circles and into the fringe.

This created a paradox. The government’s actions had:

• Created the sighting (with a U-2).
• Lied about the sighting (with a false debunking).
• Stigmatized the witness (with ridicule).

This combination created a perfect “conspiracy vacuum.” The public, including credible witnesses, knewsomething was happening, and they knew the government was lying about it. The “alien” hypothesis, already present in pop culture, became the most logical and compelling explanation for the secrecy.

“The Truth Is Out There”: The X-Files and the Modern Cover-up Myth

This cultivated distrust, which had been building for 50 years, was finally codified and delivered to a new generation by 1990s pop culture, most notably by the television series The X-Files.

The show, which ran from 1993 to 2002, was one of the most popular dramas of its decade. Its central “mythology” was not just about aliens; it was about a vast, dark, and complex government conspiracy to hide the truth about alien colonization from the public.

The X-Files was brilliant in how it wove real-life ufology into its fictional narrative. The show’s two FBI agents investigated cases that were direct callbacks to Roswell, Project Blue Book, animal mutilations, and abduction accounts. The show’s fiction co-opted the less-verifiable eyewitness parts of reality to build a “realistic mythos.”

This narrative, which reflected a deep, post-Watergate distrust of government, became the “main cultural touch point” for the phenomenon. The show’s tagline, “The Truth Is Out There,” became a cultural mantra.

For millions of people, The X-Files merged the fragmented “cover-up” story of the past 50 years into a single, cohesive, and compelling narrative. Its fiction became a more powerful and entertaining explanation for the government’s real, documented, and often clumsy secrecy (like the U-2 lies) than the more complex, less-dramatic truth. It cemented the “government is hiding the aliens” trope as the default public assumption.

The Anomalies That Endure

If the “alien” hypothesis were built only on 1950s anxieties, spy planes, and TV shows, it would have faded into history as mere folklore.

The reason it endures – and the reason it is now being taken more seriously than ever before – is the “701” problem. It’s the small, persistent, and irreducible “kernel” of genuinely anomalous data that has not gone away. These are the sightings, often by our most credible witnesses using our most advanced technology, that defy all prosaic explanation.

This modern, destigmatized “UAP” discussion, which was “re-legitimized” by a front-page New York Timesarticle in 2017, is not about “little green men.” It’s about physics and national security. This article revealed the Pentagon’s secret, modern-day UAP investigation program (the Advanced Aerospace Threat Identification Program, or AATIP) and released three now-famous “Pentagon UFO videos” captured by Navy fighter jets.

This new conversation is focused on a set of observed behaviors known as “The Five Observables.”

The Five Observables

The Five Observables are a set of flight characteristics, identified by AATIP and other investigators, that have been repeatedly observed in credible UAP reports. Their significance is that they appear to be beyond known human technology and, in some cases, beyond our current understanding of physics.

When a pilot or sensor suite reports an object displaying one or more of these traits, it is flagged as truly “anomalous.”

The Extraterrestrial Hypothesis, in this new framework, is the implied, but often unspoken, “what’s left” after all other known explanations for these observables are ruled out. If an object is real, physical, and demonstrably not a known human technology (American, Russian, or Chinese) because it violates the laws of inertia and aerodynamics, then… what is it?

Case Study: The 2004 “Tic Tac”

The most famous and compelling modern case – the “smoking gun” for proponents of the anomalous – is the “Tic Tac” incident from November 14, 2004. It involved the USS Nimitz Carrier Strike Group, which was conducting training exercises off the coast of Southern California.

This event is the modern-day equivalent of the Roswell crash – a new “origin story” that combines every element needed to sustain the ETH in the 21st century.

The Context: For two weeks prior to the incident, the advanced Aegis radar on the USS Princeton, one of the most powerful radar systems in the world, had been detecting what operators called “multiple anomalous aerial vehicles.” These objects would appear on radar at 80,000 feet (an altitude near the edge of space), drop to 20,000 feet, hover, and then shoot back out of the atmosphere. In one instance, they were tracked dropping from 80,000 feet to just above the ocean’s surface in less than a second.

The Sighting: On November 14, a training exercise was interrupted when the Princeton’s radar detected one of these objects. Two F/A-18F Super Hornets were diverted to investigate. The lead jet was piloted by Cmdr. David Fravor, the commander of the Top Gun-graduating Black Aces squadron. The second jet was piloted by Lt. Cmdr. Alex Dietrich.

As they approached the target location, their own radars showed nothing. But when Fravor and Dietrich looked down at the ocean, they saw a disturbance. The sea was calm, but in one spot, a large patch of whitewater was being “churned up,” as if a large, submerged object was just below the surface.

Hovering erratically about 50 feet above this disturbance was a 40-foot-long, white, oblong object. It was perfectly smooth, with no markings, no wings, no rotors, and no visible exhaust plumes. Fravor and Dietrich famously dubbed it the “Tic Tac.”

The Behavior: Fravor, in his lead jet, began a spiral descent to get a closer look. What happened next is the key to the entire incident. The Tic Tac, Fravor reported, mirrored his movement. As he spiraled down, it began to spiral up, as if to meet him. It demonstrated, in his words, that “it was aware we were there.”

Fravor decided to “cut it off” and flew his jet directly at the object. As he got close, the Tic Tac accelerated instantaneously and “disappeared.” Fravor described it as “like it shot off a gun.” It went from a hover to an impossible speed, with no sonic boom, in the blink of an eye.

The Corroboration: As the stunned pilots regrouped, the USS Princeton’s radar re-acquired the same object… 60 miles away, at their training “cap point.” It had traversed 60 miles in less than a minute.

Later that day, another jet was launched, this one equipped with an advanced infrared (FLIR) targeting pod. This jet did get a lock on one of the objects, capturing the famous “FLIR” video that was released in 2017.

The Impact: The Tic Tac incident is the new “gold standard” for UAP proponents. It combines:

1. Impeccable Witnesses: Top Gun navy pilots, at the top of their game.
2. Multi-Sensor Corroboration: Advanced ship radar, fighter jet radar, infrared (FLIR) camera, and four sets of human eyeballs.
3. Anomalous Behavior: It displayed all “Five Observables”: anti-gravity lift (hovering), sudden acceleration, hypersonic velocity (the 60-mile transit), and a trans-medium connection (the ocean disturbance).
4. Ascription of Intelligence: Fravor’s key, sworn testimony – “it was aware we were there” – is what moves the object from a simple “phenomenon” to an “intelligence.”

When all known human and natural explanations are exhausted, “non-human intelligence” is the only category that remains for proponents.

A New Era of Whistleblowers

The 2017 New York Times article that broke the Tic Tac story and revealed the Pentagon’s AATIP program opened the floodgates. This was followed by a stunning new development: high-level government whistleblowers.

In 2023, David Grusch, a former high-ranking intelligence official who had worked on the Pentagon’s UAP Task Force, came forward with explosive claims. In testimony to Congress under oath, Grusch alleged that the U.S. government has been running a covert, multi-decade, and illegal “reverse-engineering” program. He claimed the U.S. is in possession of “non-human” spacecraft and has recovered “biologics” (i.e., the bodies of the non-human operators).

He alleged that this information is being illegally withheld from Congress, hidden in unacknowledged “Special Access Programs” (SAPs) funded by “black budgets.”

Whether Grusch’s claims are true or false, they are the ultimate cultural fulfillment of the entire conspiracy narrative. The public already believed this was happening, thanks to the seeds planted at Roswell and watered by The X-Files. Grusch’s testimony is the “smoking gun” that connects all the dots. It alleges the government is lying (the Roswell/U-2 legacy), about the real, anomalous objects (the Tic Tac data), because they are alien.

His claims, despite lacking public evidence, are so powerful because they are the logical, expected conclusion to a 75-year-old story.

The Prosaic Sky: What Most UFOs Really Are

To maintain an objective perspective, it is essential to acknowledge the “prosaic” explanations. The “kernel of truth” represented by the Tic Tac case is, by all official accounts, extremely small. The vast majority of UAP/UFO reports – upwards of 95% – are identifiable.

The Pentagon’s All-domain Anomaly Resolution Office (AARO), the modern successor to Project Blue Book, stated in its 2024 report that it has found “no verifiable evidence of extraterrestrial beings, activity or technology.” It concludes that most sightings are “commonplace objects” and “misidentifications.”

Belief in the alien hypothesis requires dismissing, or moving past, the fact that most sightings are, frankly, boring.

Tricks of the Light and Air

Many “anomalous” sightings are simple misidentifications of natural phenomena.

• Venus: The planet Venus is the single most common explanation for “hovering” or “darting” lights. As the brightest object in the sky after the Sun and Moon, when it is low on the horizon, atmospheric distortion and a visual illusion called the “autokinetic effect” can make it appear to move erratically.
• Lenticular Clouds: These “lens-shaped” clouds are stationary, high-altitude formations that often form over mountains. They look uncannily like the 1950s “flying saucer” archetype, and it’s easy to see why they are so often misidentified.
• Meteors and Bolides: A bright meteor, or “fireball,” is a spectacular event. It can appear as a massive, fast-moving object that may seem to “break apart” before vanishing, matching many UAP reports.
• Atmospheric Plasma: Rare phenomena like “sprites” or “elves” are massive electrical discharges that occur above thunderstorms. They can look like enormous, silent, reddish-glowing “jellyfish” in the upper atmosphere, and are a perfect match for some high-altitude sightings.
• Mirages: A “Fata Morgana” is a complex superior mirage that can make objects on the horizon, like ships or islands, appear to be “floating” high in the sky.

Man-Made Objects

This is the largest category of all. The sky is now filled with “airborne clutter.”

• Balloons: According to AARO’s recent reports, balloons are the single most common prosaic explanation, accounting for as many as 70% of recently resolved cases. This includes high-altitude research balloons (a direct echo of Project Mogul), weather balloons, and even Mylar toy balloons.
• Drones: The explosion in commercial and consumer drone technology has filled the skies with objects that can hover, move in unusual ways, and display strange lighting.
• Satellites: There are thousands of satellites in orbit. They are often seen as steady, moving “stars.” But they can also “flare” brightly and suddenly when their solar panels or antennas catch the sun at the perfect angle, appearing as a sudden, bright flash that then vanishes.
• Secret Aircraft: As the U-2 story proved, secret, human-made military aircraft and experimental “black projects” remain one of the most likely explanations for high-performance sightings, especially those near military test ranges.

Ghosts in the Machine: Sensor Artifacts

This is the most important “prosaic” explanation for the modern era of UAP sightings, including the famous Pentagon videos. The very technology that makes modern sightings seem so credible – radar, infrared – can create its own “ghosts.”

The 2021 preliminary UAP report from the Office of the Director of National Intelligence (ODNI) explicitly stated that some UAP “could be the result of sensor errors, spoofing, or observer misperception.”

• The “GIMBAL” Video: This famous Pentagon video, which shows an object that seems to “rotate,” is explained by many skeptics as a common infrared artifact. The “object” is likely the heat signature of a distant, conventional jet, and the “rotation” is a glare effect inside the camera’s gimbal-based housing as it moves.
• The “GOFAST” Video: This video, which seems to show an object “zipping” at incredible speed just above the ocean, is widely and convincingly explained as a simple parallax effect. The object is almost certainly a distant, slow-moving object (like a balloon), but from the perspective of the fast-moving jet, it appears to be speeding just above the water.
• Spoofing: It’s also possible that these sensor “ghosts” are not accidental. They could be sophisticated electronic warfare “spoofing” by an adversary like Russia or China, designed to test our defenses and trick our most advanced sensors.

As our technology gets more complex, our illusions become more high-tech and harder to debunk. This makes the alien hypothesis seem more plausible, even when the data is just a “ghost in the machine.”

The Mind in the Sky: Psychological Drivers of Belief

The final, and perhaps most important, pillar of belief is not in the sky. It’s in our heads. This is not to say the phenomenon is “all in the mind,” but that our minds are primed to interpret the phenomenon in a specific way. The human brain is not a passive video recorder; it is an active “storytelling machine.”

The Brain as a Pattern-Seeking Machine

Humans are “wired to identify patterns.” It is our greatest evolutionary survival tool. We see a rustle in the grass (stimulus) and our brain connects it to a “tiger” (pattern) so we can run.

But this system is prone to errors. We are so good at finding patterns that we often find them when they aren’t there. This is called apophenia: the tendency to perceive meaningful connections between unrelated things.

In the context of UAP, an ambiguous stimulus – a distant light, a sensor glitch, a lens-shaped cloud – is fed into the brain. The brain’s “pattern-matcher” searches its database for a “cultural template.” And what template has it been fed for 75 years? The flying saucer. The X-Files. The Tic Tac.

The brain connects the dots that aren’t there and produces a “match”: It’s a craft.

This is reinforced by common cognitive biases:

• Confirmation Bias: If you already believe we are being visited, you will interpret every ambiguous video in a way that supports that belief. The “GIMBAL” video is a rotating craft; the parallax explanation is a “debunking.”
• Availability Heuristic: Vivid, recent, and emotionally-charged stories – like David Fravor’s “Tic Tac” encounter – are “available” in our minds. This makes the “alien” explanation feel far more common and true than the more boring, statistical, and complex “sensor artifact” explanation.

Profile of an Experiencer

What about the people who report these sightings? For decades, the stereotype was that they were “crazy” or “attention-seeking.”

Modern psychological research has shown this is false. Studies of people who report UAP sightings, or even “abduction” experiences, find that they generally do not have higher rates of psychopathology (like schizophrenia) than the general population.

However, studies do find strong correlations with certain personality traits and neurological experiences:

1. Fantasy Proneness: People who report these experiences tend to score higher on “fantasy-proneness.” This doesn’t mean they are lying. It means they have a richer, more vivid, and more frequent inner fantasy life. They may, in some cases, have more difficulty distinguishing an internal, dream-like state from an external, physical reality.
2. Openness to Experience: This is one of the “Big Five” personality traits. People who are high in “openness” are less likely to discount an unusual experience. When they see a strange light, their mind doesn’t “filter it out” as “just a balloon.” They remain open to the possibility that it is something truly extraordinary. This makes them more likely to (a) notice the anomaly, (b) not dismiss it, and (c) report it.
3. Sleep Paralysis: This is a major factor in “alien abduction” claims. Sleep paralysis is a common, and terrifying, neurological event. It’s a state where the mind “wakes up” but the body remains paralyzed in its REM-sleep state. The person is conscious, but cannot move, and often experiences vivid “waking dreams” or hallucinations. A common hallucination is that of a shadowy intruder or malevolent presence in the room. This experience – being paralyzed in bed, seeing a non-human entity, and feeling intense terror – is a perfect neurological seed for a memory that the brain, pulling from its cultural “X-Files” template, later interprets as an “alien abduction.”

The Quest for Meaning in an Anxious World

This is the deepest “why.” The Extraterrestrial Hypothesis speaks to one of the most significant and “ultimate concerns” of humankind: Are we alone?

This question is at the heart of the Fermi Paradox, the famous discrepancy between the high statistical probability of intelligent extraterrestrial life and the complete lack of evidence for it. “Where,” as physicist Enrico Fermi famously asked, “is everybody?”

This question implies a vast, silent, and empty cosmos. To many, this is a terrifying and isolating thought.

The Extraterrestrial Hypothesis is a psychologically powerful and comforting answer to this terror. It answers the Fermi Paradox by saying: “We are not alone. They are here. They are just hiding.”

For many people in a modern, secular world, traditional religion no longer provides satisfying answers to life’s biggest questions. The belief in “aliens” has, for some, replaced the belief in gods, angels, or other supernatural beings.

It has become, in effect, a modern, technological, and secular religion. It provides all the key functions of a traditional faith:

• A “Why” for our existence: It answers the “Are we alone?” question with a resounding “No.”
• A Sense of Meaning: It provides a grander, cosmic narrative for humanity. We are not just a random accident; we are being watched, studied, or guided.
• A Higher Power: It posits a vastly superior intelligence that is “god-like” in its technological power.

This is most obvious in the “ancient alien” theory, which posits that extraterrestrials are responsible for all human ingenuity – the pyramids, the Nazca Lines, ancient texts. Psychologically, this is a projection of our own human creative (and destructive) powers outward, onto a superior, god-like being. It’s a desire to believe that “powers greater than ourselves” are guiding us.

The ETH is a direct, technological answer to our existential isolation. It gives us a story. And it is a far more exciting and significant story than the alternatives: that the light was Venus, the radar track was a “ghost,” or that in a vast, silent universe, we are truly and completely alone.

Summary

The answer to “Why do we think UFOs are alien?” is not a single, simple fact. It is a complex, 75-year-old, self-reinforcing system – a story we’ve been telling ourselves, a story that is woven from four distinct threads.

First, the belief was forged in 1947 by a perfect, foundational storm: a “real” anomaly (Kenneth Arnold’s credible sighting of impossible speed) that was given a “brand” by the media (the “flying saucer” misquote); and a provable government lie (the Roswell “flying disc” press release, followed by the false “weather balloon” retraction) that created the “cover-up” myth from day one.

Second, the belief was nurtured by the fertile cultural soil of the Cold War. The “alien” became a perfect metaphor for our new, existential anxieties about nuclear annihilation and the “hidden other” of the Soviet Union. A pop-culture feedback loop provided a visual and narrative library that taught us what an alien encounter should look like.

Third, the belief was inadvertently strengthened by the government itself. The Air Force’s necessary secrecy around its own advanced technology (the U-2 and SR-71 spy planes) forced it to issue false debunkings to credible pilots. This “proved” to witnesses that the authorities were lying – just not about the “why.” This secrecy created a “taboo” that pushed the topic to the fringe, where only conspiracists and believers were left to define it.

Fourth, the belief endures today because of a small but persistent “kernel” of genuinely anomalous data – the 701 “unknowns” from Project Blue Book, and their modern, high-tech equivalents like the 2004 “Tic Tac” incident. These cases, backed by credible military witnesses and multi-sensor data, appear to show “Five Observables” that defy our known physics, keeping the hypothesis alive and forcing a new era of official investigation.

Finally, the belief is compelling because it speaks to a deep, human, and psychological need. Our brains are pattern-seeking machines that build stories from ambiguity. And our psyche has a deep, existential need for meaning, a need that is no longer fulfilled for many by traditional religion. The “alien” is a modern, technological, and secular answer to our oldest question: “Are we alone?”

The “alien,” then, is not just one of these things. It is the intersection of all of them: a real anomaly, wrapped in a government lie, filtered through a movie plot, and projected by a human mind that desperately wants to find meaning in the sky.
