How extraterrestrial tales of aliens gain traction
The narrative explores humanity’s intrigue with extraterrestrial entities, juxtaposing evolutionary processes with claims of alien interventions, ultimately emphasizing the need for scientific evidence over fantastical stories. Aliens!

One night, upon returning to the cave that his tribe calls home, the monkey-humanoid Moon-Watcher finds a strange crystal object, a kind of monolith that fascinates him at first, but then quickly loses his interest when he discovers that it is not edible. Soon after, the true purpose of the monolith is revealed to be none other than penetrating the minds of our ancestors to induce new abilities that, over time, will cause the development of an intelligence capable of creating new technology.
Many readers will recognise this scene from the novel 2001, A Space Odyssey, by Arthur C. Clarke, and the film of the same name, directed by Stanley Kubrick. It almost goes without saying that the crystal monolith in question is the work of an extraterrestrial civilisation that observes life on other planets and “experiments” on them to encourage the development of intelligence in as many parts of the cosmos as possible.
Seeking simple answers to complex questions
Understanding how we, as a species, came to be intelligent is one of the great enigmas of evolutionary study. Small mutations, followed by a process of natural selection to choose the most advantageous, seems too slow a process for structures as complex as the human nervous system or brain to emerge. It is this very complexity that allows millions of neurons to communicate with each other, resulting in the emergence of qualities such as the ability to respond voluntarily to environmental stimuli, or to ask questions about the very nature of humankind and the universe.
Nowadays, we know that there are evolutionary mechanisms that have lead to great leaps in terms of complexity, but that does not stop people from turning to non-human forces – Gods, extraterrestrials, spiritual energies – to explain things that are difficult to comprehend.
This has always been the case, in all human cultures. A classic example would be attributing atmospheric events – thunder, lightning, floods – to the wrath of God. These ideas came about before humans had ever left the ground, so it is no surprise that we turned our eyes even higher – to extraterrestrials – to explain other phenomena that we could only observe once travelling at high altitudes became part of our daily lives.
The allure of the unknown
The possibility that we might have been visited by beings from other worlds has always fascinated us. The element of mystery, of the unknown, only makes it more interesting.
Any phenomenon is made all the more enticing when it seems it is being covered up or hidden for secretive reasons. The attractiveness of conspiracies often leads people towards ideas which have no scientific basis, such as the belief that the Earth is flat, that humans never set foot on the Moon, or that vaccines can control our behaviour.
Even though these ideas have repeatedly been shown to be untrue, their rapid dissemination through social media, using simple, blunt language that appeals to emotion over logic, makes them very powerful weapons.
The supposed “proof” of alien visits to our planet ranges from specific Bible passages to ancient stone carvings portraying creatures or objects that may appear to be aliens or spacecraft. The latter often take the form of flying saucers.
However, we cannot forget that humans have always created imaginary creatures that resemble them and attributed them with magical powers. When imagining Gods, humans have given them a human appearance, and almost always imagined them as living in the sky.
When we look at these representations through modern eyes, we associate them with extraterrestrial beings or structures, when in fact they could be referring to a range of different things.
When unproven stories become larger than life
Recently, in the United States Congress, UFOs (currently known as UAPs: “Unidentified Anomalous Phenomena”) are back in the limelight. This is because a former air force intelligence official has made claims that the Pentagon is in possession of remains of extraterrestrial craft and “non-human biological matter”. The claims have been backed up by the testimony of a retired navy commander and a former navy pilot.
What we can be certain of is that the more we explore our skies, the more likely it is that we will encounter phenomena that we cannot explain. However, this does not mean that they are extraterrestrial. Past experience has shown us that most of these events can be attributed to optical illusions, spy or weather balloons, space junk, or even satellites that we ourselves have made.
In Spain, UFOs were a hot topic between the 1960s and the 1980s. In this era, everyone knew someone who was convinced that they had seen a UFO. This even reached the point where an exoplanet, called Ummo, was made up. It was populated by a more advanced civilisation than ours who made contact with people on Earth. In the letters these aliens supposedly sent, the ‘Ummites’ explained concepts such as genetics and cell structure.
The truth is that nowadays, reading some of these letters can be quite amusing. The story of the planet of Ummo was ultimately proved to be a monumental hoax, a fact later admitted by its own creator.
The Ummo hoax was even linked to the creation of a paedophile ring, which should make us reflect on the harmful consequences that the spread of fabricated news stories can have.
Can we deny the possibility that intelligent alien civilisations exist?
The answer, of course, is no. The universe is immense, and it is more than likely that circumstances similar to those which led to the appearance of life on Earth have been repeated on other planets. But there is a huge distance (literally and figuratively) between acknowledging the existence of these creatures and considering the possibility that they might have visited us.
Exoplanets, also known as extrasolar planets, are extremely far away, and we are limited by the speed of light which, as proven by Einstein, is the maximum possible speed at which anything can travel. Therefore, the journey to even a “nearby” exoplanet would take thousands of years. Maybe a civilisation more advanced than ours could find a way to do it faster, but not to the point of it being something easy or commonplace.
In any case, if the remains of alien life or spacecraft are stored away somewhere, why are they not being shown to us? Scientists would jump at the chance to analyse this organic matter to find out how it is structured, how it metabolises energy, or what molecules it uses to store genetic information.
Until there is proof, this is not a question of science, but rather, of stories. Stories can be very entertaining, but these kinds of stories do not help us to build a more accurate or helpful view of the world.

The Unfavorable Semicircle Mystery: The YouTube Channel That Uploaded Tens of Thousands of Cryptic Videos
In 2015, the YouTube channel Unfavorable Semicircle gained attention for its enigmatic and abundant video uploads, totaling over 70,000 before its deletion in 2016. Theories about its purpose vary, from automated content generation to digital art experimentation, leaving its intent unresolved.
In the vast digital landscape of the internet, strange phenomena occasionally emerge that leave investigators, tech enthusiasts, and everyday viewers scratching their heads. One of the most puzzling cases appeared in 2015, when a mysterious YouTube channel called Unfavorable Semicircle began uploading an astonishing number of cryptic videos.
Within months, the channel had published tens of thousands of bizarre clips, many of which seemed random, incomprehensible, and visually chaotic. But as internet detectives began analyzing the content more closely, they discovered that these videos might not have been random at all.
The Sudden Appearance of an Internet Mystery
The Unfavorable Semicircle channel reportedly appeared in March 2015, with its first uploads arriving in early April.
Almost immediately, the channel began publishing videos at an incredible pace. Observers estimated that the account uploaded thousands of videos per week, sometimes multiple videos per minute. By the time the channel disappeared in early 2016, researchers believed it had uploaded well over 70,000 videos, possibly far more.
The scale alone made the project seem impossible for a human to manage manually.
Strange Visuals and Cryptic Titles
Most of the videos shared similar characteristics:
- Extremely short or very long runtime
- Abstract visuals such as flashing colors, static, or distorted imagery
- Little or no audio, or heavily distorted sounds
- Titles made of random characters, symbols, or numbers
To casual viewers, the videos looked like pure digital noise. However, online investigators suspected something more deliberate was happening.
Hidden Images Discovered
The mystery deepened when researchers began extracting individual frames from some videos.
When thousands of frames from certain clips were stitched together, the results sometimes formed coherent images. One of the most famous examples involved a video titled “LOCK.” While the footage appeared chaotic at first, combining the frames revealed a recognizable composite image.
This discovery suggested the videos were carefully constructed rather than random uploads.
Theories About the Channel’s Purpose
Because the creator never explained the project, several theories emerged across Reddit, YouTube, and internet forums.
Automated Experiment
Many believe the channel was created using automated software that generated and uploaded content at scale.
Alternate Reality Game (ARG)
Some viewers suspected the channel might be part of a hidden puzzle or digital scavenger hunt.
Encrypted Communication
Others compared the channel to Cold War “numbers stations,” suggesting the videos could contain coded messages.
Digital Art Project
Another theory suggests the channel was an experimental art project exploring algorithms, data, and visual noise.
Despite years of investigation, no single explanation has been confirmed.
Why the Channel Disappeared
In February 2016, YouTube removed the channel, reportedly due to spam or automated activity violations.
By that time, the channel had already become a minor internet legend. Fortunately, some researchers managed to archive a large portion of the videos before they disappeared.
Even today, archived clips continue to circulate online as investigators attempt to decode them.
Other Mysterious YouTube Channels
The Unfavorable Semicircle mystery is not the only strange case on YouTube.
One well-known example is Webdriver Torso, a channel that uploaded hundreds of thousands of videos showing red and blue rectangles with simple beeping sounds. Internet speculation ran wild before Google eventually confirmed it was an internal YouTube testing account.
Another example is AETBX, which posts distorted visuals and unusual audio that some viewers believe contain hidden patterns or encoded information.
These cases highlight how automation, experimentation, and creativity can sometimes blur the line between technology and mystery.
A Digital Mystery That Remains Unsolved
Nearly a decade later, the true purpose behind Unfavorable Semicircle remains unknown.
Was it a sophisticated experiment? A piece of algorithmic art? Or simply an automated test that accidentally captured the internet’s imagination?
Whatever the explanation, the channel stands as a reminder that even in a world filled with billions of videos and endless information, the internet can still produce mysteries that challenge our understanding of technology.
Why Internet Mysteries Still Fascinate Us
Stories like Unfavorable Semicircle capture attention because they combine technology, creativity, and the unknown. They invite people from around the world to collaborate, analyze patterns, and search for meaning hidden in the noise.
And sometimes, the most intriguing part of the mystery is that the answer may never fully be known.

For decades, the idea of aliens visiting Earth has lived in a cultural no-man’s-land: too fascinating to ignore, too stigmatized to study seriously, and too easy to dismiss with a joke. But that posture has shifted in a measurable way over the past several years.
Physicist Kevin Knuth (University at Albany, SUNY) argued in a 2018 essay for The Conversation that the question of whether some UFO reports could represent something truly unknown is worthy of serious scientific study — not because we have proof of extraterrestrials, but because a small portion of cases appear to resist easy explanation and involve trained observers, multiple sensors, or unusual performance claims.
Article: https://theconversation.com/are-we-alone-the-question-is-worthy-of-serious-scientific-study-98843
That argument gained new oxygen in late 2017, when The New York Times reported that the U.S. Department of Defense had funded a program known as the Advanced Aerospace Threat Identification Program (AATIP). The reporting described roughly $22 million spent to examine military reports of unusual aerial incidents. Former Pentagon official Luis Elizondo became a central public figure in the story, saying he left his role amid frustration over secrecy and limited support for deeper investigation.
Around the same time, the Pentagon confirmed and released several now-famous military videos showing encounters recorded on forward-looking infrared (FLIR) systems from Navy aircraft — clips that reignited public debate and pushed the topic out of late-night-TV territory and into mainstream news.
What we’ve learned since (2018–2026)
The biggest “update” since your original post isn’t a single smoking gun. It’s the fact that the U.S. government and scientific institutions have increasingly treated the issue as a data and airspace-safety problem—and, potentially, a national security one.
A few key developments:
- The language changed: “UFO” has increasingly been replaced by UAP (Unidentified Anomalous Phenomena), a term meant to reduce stigma and widen the scope beyond “flying saucers.”
- Regular reporting became normalized: The Office of the Director of National Intelligence (ODNI) has issued public-facing UAP reporting in recent years, and the Department of Defense has continued formal tracking through dedicated offices.
- NASA stepped in: NASA convened an independent UAP study team, releasing a final report in 2023 that emphasized something simple but important: if you want answers, you need better data, consistent reporting standards, and transparent methods. (NASA’s stance was not “aliens confirmed,” but “this is a legitimate area for structured inquiry.”)
The Carl Sagan test still applies
Carl Sagan’s line remains the guardrail here:
“Extraordinary claims require extraordinary evidence.”
In other words: eyewitness testimony alone — even sincere testimony — isn’t enough. A personal story, a viral clip, or even a dramatic encounter doesn’t automatically equal proof of extraterrestrial visitation. If the claim is “non-human intelligence is visiting Earth,” the evidence has to be strong enough to survive serious scrutiny: repeatable analysis, multi-sensor confirmation, chain-of-custody, and independent review.
So where does that leave us?
If you strip away the hype, the most reasonable position in 2026 looks something like this:
- Something is being observed in a small percentage of cases that isn’t immediately identifiable.
- That does not automatically mean “aliens.”
- But it does mean the topic is no longer intellectually off-limits the way it once was.
After leaving AATIP-related work, Elizondo became associated with To The Stars Academy of Arts & Science, a group founded by musician Tom DeLonge that aimed to blend public interest, aerospace ideas, and advocacy for further investigation. Whether you view that effort as serious research, public outreach, or a media-adjacent project, it reflects the broader reality: the conversation has moved from fringe forums into public institutions.
The next step shouldn’t be louder claims. It should be better instrumentation, better reporting, and better science—because if there’s a prosaic explanation, rigorous study will reveal it. And if there’s something genuinely novel in the data, that’s exactly what science is for.

Former President Barack Obama recently sparked headlines, social media debates, and a fresh wave of UFO chatter after a brief remark during a podcast interview. The comment quickly ricocheted across news outlets, with many asking: Did Obama just confirm aliens exist? And just as quickly, Donald Trump weighed in.
Let’s unpack what was actually said — and what it means.
🎙️ The Comment That Ignited the Conversation
During a rapid-fire question segment on a podcast hosted by Brian Tyler Cohen, Obama was asked directly:
“Are aliens real?”
Obama’s response:
“They’re real, but I haven’t seen them.”
That short answer fueled immediate speculation. Clips spread online, often stripped of context, with some interpreting the statement as a bombshell confirmation of extraterrestrial life.
🧠 What Obama Meant
Soon after the comment gained traction, Obama clarified his meaning.
His explanation aligned with a position he’s expressed before:
✔ He was referring to the statistical likelihood of life elsewhere in the universe
✔ He was not claiming evidence of alien visitation
✔ He emphasized that during his presidency he saw no proof of extraterrestrial contact
In other words:
Obama was speaking philosophically and scientifically — not revealing classified information.
This interpretation matches mainstream scientific thinking: given the size of the universe, life beyond Earth is plausible, but confirmed evidence remains elusive.
🛸 Why the Comment Resonated
The remark landed in a cultural moment where:
• Interest in UAPs (Unidentified Aerial Phenomena) is high
• Government transparency around UFO reports has increased
• Space exploration discoveries (exoplanets, water worlds) dominate science news
Even a casual statement from a former president can ignite intense discussion.
🇺🇸 Trump’s Reaction
Former (and current political figure) Donald Trump responded critically.
Trump characterized Obama’s comment as:
• A “mistake”
• Potentially involving “classified information”
He also reiterated his own stance:
He does not know whether aliens are real.
Trump pivoted the conversation toward disclosure, suggesting he would support or consider declassifying UFO/UAP-related files — a theme that has periodically surfaced in political rhetoric.
⚖️ Politics vs Interpretation
Trump’s reaction highlights how statements about extraterrestrial life often become political flashpoints, even when the original comment is speculative or philosophical.
Key distinction:Obama’s Clarification Public Interpretation Life elsewhere is likely “Obama confirmed aliens” No evidence of contact “Government disclosure”
🔬 The Scientific Reality
Organizations like NASA and the broader research community maintain:
✅ Life beyond Earth → statistically plausible
❓ Intelligent civilizations → unknown
❌ Confirmed alien contact → no verified evidence
Investigations into UAPs consistently conclude:
• Most sightings have conventional explanations
• Some remain unresolved due to limited data
• None confirmed as extraterrestrial craft
🌌 Why These Stories Keep Captivating Us
Conversations about aliens sit at the intersection of:
✨ Science
🧠 Curiosity
🛸 Mystery
🎭 Pop culture
🏛️ Politics
When a former president comments, the intrigue multiplies.
📌 Bottom Line
Did Obama say aliens are real?
Yes — but in the sense that life elsewhere in the universe is likely, not that aliens are visiting Earth.
Did he claim evidence?
No.
Trump’s response?
Critical, skeptical, and framed around classification and disclosure.
