25 Oddities That Might Convince You Life Outside Our Planet Exists

Posted by , Updated on April 29, 2015

Are we the only living species in the universe? This question has been asked since ancient times and remains without a definitive answer despite many people believing there are alien life-forms out there and “evidence” that supports this belief. As Ellen DeGeneres once confessed,

“The only thing that scares me more than space aliens is the idea that there aren’t any space aliens. We can’t be the best that creation has to offer. I pray we’re not all there is. If so, we’re in big trouble.”

Check out these 25 Oddities That Might Convince You Life Outside Our Planet Exists!


Wow! Signal

Wow! Signal

This signal was a strong narrowband radio signal detected by Ohio State University researchers on August 15, 1977. The signal bore the hallmarks of non-terrestrial and non-solar system origins.


Numerous UFO Sightings

UFO Sighting

Reports of flying objects in the night (or day) sky are not a recent phenomenon. From the third century BC there have been many accounts indicating the appearance of strange objects in the sky. Recently, plane passengers of a West Asian Airline claimed to have witnessed a disc-shaped object while flying over Iran, with the fast-moving object not resembling a plane nor a helicopter.


Emperor Theodosius Reportedly Had An Alien "Experience"

Emperor Theodosius

A remarkable testimony of Alien existence is an account from Byzantine Emperor Theodosius around 390 CE. The emperor described a brilliant glowing orb in the sky with a great number of other glowing orbs drawing near the larger one, almost as if they were being pulled in. Theodosius claimed the spectacle to be like a swarm of bees flying around a beekeeper until they blended together into one, becoming as bright to the eye as a double-edged sword.


Mars Canals

Mars Canals

The idea that Mars was traversed by a complex network of canals was first put forward in 1877 by Italian astronomer Giovanni Schiaparelli, and later popularized by astronomer Percival Lowell. Lowell made intricate drawings of what he took to be canals based on observations he made at his observatory in Flagstaff, Arizona. The idea gained relatively wide acceptance until the early twentieth century, when astronomical observations improved and higher-resolution imaging revealed the “canals” to be optical illusions and geologic formations.


Radio Signals

Radio Signals

Scientists are trying to explain what is causing a series of mysterious signals, known as Fast Radio Bursts, which are coming from beyond the solar system. Could this be a transmission from an alien civilization?


Cloudy life on Venus


Scientists theorize that there might be life on Venus’s clouds. In spite of Venus’s hot, acidic surface; 50 kilometers up the moist atmosphere, conditions are a bit more hospitable with a temperature of 70°C and a pressure similar to Earth’s.


Martian Methane

Martian Methane

A team of NASA and university scientists has detected very high amounts of methane in Mars’ atmosphere, which indicates that the planet is still alive, in either a biologic or geologic sense.


Near Air Collision

Near Air Collision

Stories of near-collisions involving a cigar-shaped UFO and commercial airplanes are endless in number. Many pilots have reported that cigar or rugby ball–shaped objects have passed within a few feet of their planes’ cockpits. A recent incident involving one of Air China’s jets could be more than conjecture. The plane was forced to make an emergency landing after an unexplained occurrence ruined its cone. Was it a collision with a flying disc that came out of nowhere? Some believe this to be the case.


Harsh Environments


Evidence for the possibility of life outside our planet, could ironically be found here on earth. Life can be found in the harshest of environments, from the cold dark depths of our oceans to the aftermath of super heated volcanic lava. Scientists believe that if life could live within our planet’s harsh extremes, then life could also live within similar extremes outside our planet (say beneath the surface of Mars).


African Cave Painting

African Cave Painting

An African cave painting depicts a being wearing headgear with antennae and flying through the air. The being has large black, slanted eyes, thin lips, and is holding an animal in its arms.


Medieval Tapestry

Medieval Tapestry

In the foreground of a medieval tapestry in the Collégiale Notre-Dame, in Beaune, France, is a depiction of the Virgin Mary but in the background is a clear rendition of a flying ship. Was this an artists witness to something really weird while painting the Virgin Mary?


The 1561 UFO Incident Over Nuremberg

The 1561 UFO Incident Over Nuremberg

An old woodcut created by Hans Glaser in 1566 clearly depicts a battle between flying disks and cylinders that occurred over Nuremberg, Germany, on April 4, 1561 in what is believed to be the first mass sighting of celestial phenomena and unidentified flying objects in history.


Jupiter’s Moon Europa

Jupiter’s Moon Europa

According to scientists, the quantity of water contained beneath Europa’s icy crust, which is shielded from harmful radiation, is one of the solar system’s best chances for finding alien life and a good indicator that some might already exist.


The Roswell Incident

The Roswell Incident

According to many theories, in 1947, an alien spacecraft, with its crew aboard, crashed in Roswell, New Mexico. Ever since then, Roswell has been called the world’s most famous, most exhaustively investigated, and most controversial UFO claim in history.


The Great Los Angeles Air Raid

Great Los Angeles Air Raid

This incident occurred less than three months after the United States entered World War II, on February 24, 1942, and that’s why initially the target of the aerial barrage was thought to be an attacking force from Japan. But the main reason why it was later believed to be a UFO was the fact that even though the unidentified object was hit multiple times by antiaircraft fire, it appeared to be undamaged and soon disappeared into the night, never to be seen again.


Ancient Signs

Egyptian hieroglyphics

The Egyptian hieroglyphics found in the Temple of Seti I at Abydos have been interpreted as featuring out-of-place artifacts that depict a helicopter as well as other examples of modern day technology. Some argue that this is evidence of aliens in ancient times. However, there is a strong argument that states these hieroglyphs to be the result of Ramessess II’s attempt to steal credit for the built temple (and thus inscribing his name on top of Ramassess I’s name).


Drake Equation

Drake Equation

The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. It was first presented by Frank Drake in 1961 and identifies specific factors thought to play a role in the development of such civilizations.


Old Illustrations

Ume No Chiri

An 1803 illustration from Ume No Chiri depicts a real-life artifact found by a Japanese sailor. Its exterior was iron and glass and the inside featured the strange letters pictured in the drawing. Was this the creation of a vivid imagination, or was the artist inspired by technology beyond the times?


Australian Rock Art

Australian Rock Art

Predominantly found in the remote Australian northwest Kimberly region, there are ancient drawings (known as Wandjina paintings) on rocks that show beings with enlarged bald heads, large slanted eyes, and no mouths. Aliens maybe?


Area 51

Area 51

The US Air Force acquired the area in 1955 and all the research about possible sightings or alien landings associated with the place is well guarded. Its secretive nature and undoubted connection to classified aircraft research, together with reports of unusual phenomena, have made Area 51 a focus of modern UFO conspiracy theories.


Apollo 11’s UFO sighting

Apollo 11

In a documentary about the Apollo 11 space mission, the astronauts stated without reservation that they saw a UFO that kept pace with them for a time while on their journey to the moon. Though explanations for this UFO sighting range from the rocket that had separated from the main craft to the sun reflecting off the detached panels.


Alien Scorpions

Alien Scorpions

A published article in the Russian Solar System Research magazine claimed that a Soviet probe actually captured images of alien life (creatures that looked like scorpions) on Earth’s scorching sister Venus back in 1982. (Though it’s important to note that most scientists have attributed this “scorpion” to faulty camera lenses).


Alien Fossils

Alien Fossils

NASA’s scientists have recently found tiny fossils of bacterial alien life-forms in the remnants of a meteorite that landed on Earth.


Alien Abduction

Alien Abduction

Throughout the years many people have claimed to have been abducted by aliens. Though these kind of claims warrant skepticism, it’s not outside the realm of possibility for these claims to have some merit. Most notably a few year ago a victim from Gulf Breeze, Florida, claimed, a “large human-like figure” took a sample from his spine with a syringe while he was sleeping in his home. Was this truly intelligent life performing research on this man, a mere hallucination, or an elaborate hoax?


The Known Universe Itself

Milky Way Galaxy

Technically speaking, there is no direct proof that life outside our planet exists, at least not yet. Nevertheless, our universe is home to a lot of stars, and about half of them (that we know of) harbor planets. It’s difficult to believe that our planet is the only planet that has gone through life sustaining changes. It’s not entirely out of the realm of possibility, but it’s more likely that there is indeed life out there somewhere and we just haven’t found it yet.
