Could the truth about an extraterrestrial presence on Earth be part of a UFO Conspiracy?

  • The ancient site of Gobekli Tepe challenges everything modern archaeologists believe about mankind's past. The megalithic stone complex was built over 12,000 years ago, which dates it to 6,500 years before Stonehenge, and 5,000 years before the first known civilization was said to have emerged in Mesopotamia. Mainstream archaeologists believe that humans were roaming the Earth as simple hunter-gatherers at this time, but if so, how could they have built such incredible structures? Might they have had help from a more advanced--perhaps extraterrestrial--civilization? According to Ancient Astronaut Theorists, the site serves as the smoking gun for a lost civilization--one whose survivors may have built the site to preserve important information about otherworldly visitors. Does the site offers clues about our extraterrestrial past that the ancients felt compelled to preserve for future generations?

  • Hundreds of strange disks are discovered in a cave in China that appear to tell the story of an ancient extraterrestrial crash on Earth. Shortly after the disclosure of these artifacts, the disks are confiscated by the Chinese government and dismissed as a hoax. But are they? Ancient traditions from around the world speak of mysterious disk-shaped artifacts that held tremendous power. The Babylonians claimed to have a disk that stood in for their most powerful deity. The Incan leader Pachacuti attributed his rise to a divine disk that fell from the sky. And treasure hunters have been searching for centuries for the acclaimed "Golden Sun Disk" that was hidden from the Conquistadors when they sacked Peru. Ancient Astronaut theorists propose that these disks were more than just sacred objects, and represent some sort of extraterrestrial technology.

  • In Honshu, Japan, stands one of the country's oldest and holiest Shinto shrines, the Ishi-no-Hoden. Carved from a single rock, it appears to hover over a pool of water and depicts a sky ship of stone that the ancient people witnessed descending from the heavens. This is just one of numerous megalithic structures found throughout Japan commemorating a time when the gods, or perhaps, extraterrestrial beings, descended to Earth.
