Evidence Aliens COULD Exist

So many of the aliens we see in movies and television seem much more magical than their science fiction label might suggest. Jedi have magic powers, alien visitors can read our minds and speak our languages at first contact, and let’s not talk about the impossibility of moving at lightspeed. And yet, scientists haven’t given up hope that there’s life out in the stars and they’re right not to. Here are 5 pieces of evidence that show that aliens might exist out in the universe.

5 - Project BLUE BOOK
In 1952, the United States government began a top-secret project called Project BLUE BOOK to look into the truth behind supposed spaceship sightings. Identifying and debunking those sightings were of the utmost importance at the time. With tensions high between the U.S. and Russia, it was necessary to know what threats might be lurking in the skies and who -- or what -- was behind it.

Project BLUE BOOK ran until December 17, 1969, 5 months after the Apollo 11 launch, and has since been declassified. The records are now fully available in the National Archives and during its 17 years of operation, 12,618 sightings were recorded. Most were debunked, but not all of them. To this day, 701 are still left unidentified, and the search for UFOs by the U.S. government finished inconclusively… at least officially. For now, what we can say for sure is that UFOs -- unidentified flying objects -- exist. Whether or not they are spacecraft that contain little green men is yet to be seen. Evidence, however, shows that there is a possibility that aliens not only exist but they’ve been vacationing on Earth for years.


4 - Goldilocks Zones
Goldilocks zones are regions around stars that could be habitable for life. As you might guess, these areas are not too hot or too cold, but just right. Earth, for example, falls in the sun’s goldilocks zone but, surprisingly, we’re not neatly in the center like we once thought. Scientists recently changed the parameters for defining these areas, meaning the places we’ve been looking at will have to change too. Places we once thought were habitable are now not, and those we thought impossible are now completely fair game for greater exploration.
Some planets, like Gliese 581d, are now even more likely to be able to harbor alien life. Before this change, 581d had been on the outskirts of its system’s goldilocks zone, but now it’s sandwiched in the middle. With this new definition of habitability, it’s incredible to think that maybe aliens were always there -- we were just looking in the wrong places.

3 - Where There’s Water, There’s Life
Liquid water, our beautiful H2O, is something all humans and every other creature on Earth need to survive. It’s also one of the main features that scientists look for when searching for extraterrestrial life. As it turns out, water’s not uncommon in the universe. It’s not even uncommon in our solar system, even far beyond where scientists widely consider habitable for life. Water flows beneath Mars’ surface. Liquid water may exist in Venus’s scorching atmosphere. Some of our gas giants’ moons have water hidden underground.

Jupiter’s moons Europa, Callisto, and Ganymede all contain vast oceans beneath their rocky, icy surfaces. Scientists hold hope that one of these oceans may contain life within them, and the European Space Agency is taking steps to discover the truth. In June 2022, the Jupiter Icy Moons Explorer mission, or JUICE for short, will launch a probe to explore in-depth not only Jupiter’s atmosphere and rings but Europa, Callisto, and Ganymede as well. The ESA states its main objective to be understanding the conditions for why these three moons can habitable for life so far out of the goldilocks zone. If we’re lucky, they may soon find that something dwells beneath those icy surfaces.

2 - Living Life to the Extreme
Alien life doesn’t just mean big bulbous heads or living long and prospering or any other sentience we’re used to considering alive. Just because plants don’t think doesn’t mean that they aren’t alive, after all. Similarly, there are microbes -- small and unthinking and nevertheless alive -- in some of the most extreme environments around the world. Whether in freezing ocean depths or boiling thermal vents, life finds a way and it finds a way to thrive.
With the definition of life as broad as it is, our classification of what we’d call “aliens” is just as broad. Scientists have stated that as long as there’s liquid water, there can be life. And as we know, we have 6 possible places to explore just in our Solar System where life may be possible. There are even microbes here on Earth that could survive beneath Mars’s surface. With this in mind, the question becomes not can life exist on another planet, but does it already?
