10 Crazy Conspiracy Theories About Extraterrestrial Beings

Gregory Myers


The idea of other intelligent beings has long been fascinating to us. Ancient myths have us interacting with gods and all kinds of strange, mythical creatures such as centaurs. The stars have also played an important role in cultures around the world. Over time, ancient myths became nothing more than legends, while technology and scientific discovery started to destroy our belief in strange nonhumans.

This made us look further to the stars for our hopes, and all-new theories have been born since. Many of today’s theories about intelligent, nonhuman life are not only bizarre but try to trace everything back to ancient days. Modern conspiracy theorists believe that everything is connected and that the events of Roswell were not even close to the beginning.

10The Mass UFO Sightings Over Los Angeles Decades Ago

Before Roswell, a strange incident happened that might have gotten way more attention in history books if not for the fact that it happened in the middle of World War II. In 1942, several years before the infamous Roswell incident, the city of Los Angeles was in an extremely tense mood. The Japanese had only recently bombed Pearl Harbor, so anything strange in the sky was immediately assumed to be a Japanese air raid.

On the night of February 24, 1942, residents of Los Angeles saw many unidentified aircraft in the sky. Everyone started panicking, thinking that the aircraft were Japanese bombers. However, despite the city launching an all-out, coordinated attack against these strange objects in the sky, there’s no physical evidence that they managed to hit anything, nor is there any evidence that the UFOs attempted to fire back or interact in any way.

Some witnesses claimed to have seen objects shaped like lozenges. Poor-quality pictures taken from that night make it look like there’s a stereotypical alien ship ominously hovering over Los Angeles. To add fuel to the fire, the Navy and Air Force gave contradicting reports on the incident. The incident may seem very mysterious, but there was a massive war going on. It may simply have been experimental technology of some kind. We may never know.


9The Crawling Space Slug On Pluto

Recently, NASA made history by making brand-new, color photos of Pluto that we had never seen before and getting close enough to make interesting, new observations. Before long, people were speculating about what NASA may have covered up and what it may have “leaked” to the public about alleged alien life. One photo in particular caught the eye of conspiracy theorists, who insisted that it showed a gigantic alien space slug slowly moving across the surface of the planet. While the gigantic moving object does look vaguely like a slug, it—unfortunately—is not an example of alien life.

However, the explanation given by NASA is still pretty interesting. The folks at NASA claim that what people saw was a gigantic chunk of nitrogen-rich ice that floated to the surface of Pluto only to slowly melt and sink below again. Experts say that this behavior on the surface of Pluto is very similar to that of a lava lamp. The “slug” people saw was a block of this ice floating temporarily on the surface before slipping beneath the waves. It may not be alien life, but a vast part of an entire planet’s surface acting like one giant lava lamp is pretty cool, too.

8The Giant People Who Live Under The Earth’s Crust

Most people look to space in the hopes of finding alien life; others search among us for those who may be “hybrids.” Yet there are also those who are convinced that much of the world above us is a sham and that the true secrets are beneath our feet—beneath the Earth. With the advent of social media, conspiracies that suggest that the Earth is nothing like people think are becoming more popular.

While many theorists like to claim that the Earth is flat, others say that it is hollow and that there is a completely separate world inside of it, which somehow has its own, functioning Sun despite being inside our Earth. According to these conspiracy claims, Admiral Byrd did not actually fly over the North Pole in the 1940s—he flew inside it. He discovered another world inside the Earth’s crust, and the government has been doing its best to cover up the story ever since.

Some conspiracy theorists also take seriously an old legend from a group of Scandinavians who were sailing and ended up near the Pole. The Scandinavians thought it strange that it started to get warmer instead of colder, and they suddenly found themselves sailing inside the Earth. They found a fantastic land full of rich bounty and kind, giant people who ate similarly giant fruits and vegetables. According to the conspiracy theorists, these beings are much smarter than we are and sometimes communicate through intermediaries in order to try to better steer humanity’s fate. Some even claim they secretly talk to the Dalai Lama.



7The Secret Reptilian Aliens Who Control The World’s Governments

Most of us are already well aware of the theory about reptilians dreamed up by David Icke. The claim is that long ago, alien beings seeded themselves among us and held on to their power through the ages by keeping it in the family. Whether they have managed to keep all knowledge of their original roots or ways depends on the theory, but the claim is that these people are at least hybrids, are aware of it, and are using their connections and power to control the world. However, what many people don’t realize is that the main point of this theory is even more ridiculous than that.

The truth is that many details about the prior history of these reptilians were added to this theory much later to make it sound more plausible. The theory’s actual main evidence is simply that most people who are royalty or have spent time in a higher office are distant cousins or otherwise related. At the very least, people suggest that this is some kind of a conspiracy, even if it is not an extraterrestrial one.

However, all those people being related is not really that strange. Anyone who’s played the game “Six Degrees of Kevin Bacon” knows the theory that no two people are more than six people away in terms of introduction. Seeing how back in the day, many royal families married for political expediency, it doesn’t seem very odd that people in royalty or politics are distantly related or at least connected by marriage.

6The Alien Woman Supposedly Spotted On The Martian Landscape

With the advent of the Internet, the community of conspiracy theorists has grown at an accelerated rate. These theorists are able to go through thousands of publicly available photos from NASA in the hopes of finding alien life or some evidence of suspicious government activity and quickly affirm the most bizarre theories inside their echo chamber of unreason and paranoia. Others are simply obsessed with the idea of finding alien life and will often convince themselves of its existence when there is no reason to think so.

A good example of this is the “Martian woman” story that popped up in 2015. People were sharing a photo taken by the Mars Curiosity rover that showed what some claimed to be an alien woman on Mars. As you might imagine, the photo was extremely unclear. Many people compared calling the image a person to seeing shapes in the clouds: the stirrings of imagination and nothing more. Others went so far as to claim that a rock in the picture might be the alien’s “house.”

CNET followed the story and could not get an explanation from NASA beyond their spokespeople saying it was likely people’s overactive imaginations. However, while they didn’t hear back from NASA, the folks at CNET did analyze the other photos from Mars Curiosity. They pointed out that, based on the rover’s scale, if the “woman” were an alien being, she would be an incredibly small fraction of our size.

5The Real Men In Black May Be Our Government Messing With Us

While many suspect that the government is trying to hide the existence of alien life, some people think that it may actually be more complicated than that. According to them, there is evidence that former government agents have infiltrated UFO enthusiast circles and fed them fake information about UFOs, even going so far as to suggest that there was more government information to spill than there actually was.

Sometimes, these agents allegedly had full institutional help in order to fool gullible UFO enthusiasts. They even helped plant fake evidence to get people more riled up about the subject. This also gave the agents a way to monitor UFO groups to see if they were getting close to figuring out any of the actual military projects the government was working on, which was especially important at the time because they didn’t want the Russians to get wind of it.

This conspiracy theory suggests that the vast majority of alien lore is actually the government trying to intentionally confuse us in order to keep us and the Russians away from the truly important projects. This was also a great way for the government to explain away any strange things that happened due to experiments that didn’t go as planned.



4Governments Are Aware Of More Than 80 Distinct Alien Species

Many theorists claim that governments around the world have already made contact with at least one alien species. Usually, the claims are that these aliens are benign and wish to help us or work with us in some way. There have also been stories about government officials coming out and saying there’s more going on than the public is being told. However, one particular story is unique in that its claims are far beyond the usual.

The theory goes that a high-up Canadian official confirmed that we contacted multiple alien species and worked with several different ones over the years. Where it gets even more insane is when the theorist claims that—thanks to information gleaned from government officials—we know there are at least 80 distinct, intelligent species of aliens.

Of course, the theory is somewhat hurt by the descriptions of these “alien” races. The vast majority of them look a lot like humans and read more like descriptions of different races in a video game than they do actual alien species. The more unique-looking ones are supposedly able to shift forms and move through different dimensions. For what it’s worth, the theorist emphasizes multiple times that he or she is “not just making this up.”

3Venus Was Once Host To Earth-Like Life

Venus has long been known as Earth’s sister planet, despite the fact that Venus spins its own way in the universe and has an atmosphere that is incredibly toxic to those who live on our planet. The reason for the “sister” status is that scientists believe that Venus may have once been very much like Earth. It’s believed that Venus once had a lot more water on it and lost it over time. Some theories have suggested that Venus ended up with a runaway greenhouse gas effect on a level way worse than anything we are dealing with on Earth. Eventually, these greenhouse gases ended up causing Venus to lose its water and turned its atmosphere into something inhospitable to human life.

In recent years, studies have further confirmed this, suggesting that Venus was once a water-rich planet and may have been capable of supporting intelligent life of the human variety. This has led conspiracy theorists to wonder if perhaps Venus once was home to human-like species or if some Venusians managed to survive the cataclysm and evolve into a new breed of intelligent beings. The idea of intelligent life so close to Earth is very exciting to alien theorists.

2Jesus Christ Was An Alien-Human Hybrid

For the longest time, most alien conspiracy theories focused on the time period between the Roswell incident and the present day. Recently, we have seen a rash of theories about alleged ancient alien visitors who came to our planet millennia ago and changed our culture and history forever. These theories tend to claim that if something done by ancient people can’t be explained with our knowledge of their technology, it was therefore done by alien visitors with technology far superior to ours. Many of these theorists believe that aliens lived among us through the early days of recorded history, and that some of them, or at least their hybrids, might still be alive today.

One of these theories suggests that Jesus Christ was actually an alien-human hybrid. The theorist points out that there are great similarities between the dream visits Mary receives and some of the strange stories you hear of people being abducted by aliens. They also suggest that the virgin birth was possible because the aliens artificially inseminated Mary during one of their abduction experiments.

The theorist goes on to point out all the important people in history who have similar origin stories of either a virgin birth or some kind of hybrid birth involving a so-called “god.” The suggestion is that many of our important figures were designed by aliens in order to influence the path of humanity. These figures would include the vast majority of early religious thinkers and philosophers.

1Human DNA Has Been Irrevocably Tampered With And Altered By Past Alien Visitors

The same people who believe that ancient alien visitors are responsible for the pyramids, Jesus, the Hanging Gardens of Babylon, all of the Mayan ruins, the Easter Island heads, and anything else made by early man, are also convinced that humans themselves could not have achieved their place in the world without the help of ancient aliens. Essentially, such theorists have decided to replace the traditional God with a group of nebulous sentient beings with vague motivations and advanced technology that might as well be magic, as far as our understanding is concerned.

Many not only believe in alien-human hybrids but think that human DNA was at one point greatly altered by alien visitors, either to jump-start our evolution, make us into better worker drones for the aliens’ purposes, or just to experiment on us to see what would happen. Recently, conspiracy theorists went crazy at the news that human DNA appeared to have foreign DNA in it, which couldn’t have occurred through natural evolution.

The explanation from scientists is that the foreign DNA is from microorganisms that were present in the same environment as developing humans, but the theorists are convinced that it is the result of deliberate tampering by ancient alien visitors.
