It's perhaps one of the most controversial topics and widely debated subjects in modern history: Does intelligent alien life exist? It seems people around the world have always speculated the existence of aliens, asserted government cover-ups, and shared their versions of alien encounters. In the 1960s, the U.S. experienced a surge in the interest of extraterrestrial life after a weather balloon fell over Roswell, New Mexico and subsequently incited a rash of theories linking aliens, top secret government facilities and general fandom. Crop circles, the mysterious Area 54, alleged sightings and meetings are parts of a complex puzzle.
While it can be easy to dismiss some claims made by staunch believers in other-worldly life, if the universe is so vast and humans have inhabited Earth for so long, why haven't we encountered aliens yet? Or maybe even stranger: what if we are the aliens? Check out this playlist to get at the heart of the debate and decided for yourself: What else is really out there?
