Shiva the Destroyer

Of the millions of Hindu gods, none is more important than Shiva--the great destroyer. Ancient Astronaut theorists suggest this powerful being that possessed flying machines, incredible weapons, and had supernatural abilities may, in fact, have been the leader of an extraterrestrial faction that came to Earth wielding advanced technology. And the evidence, they say, comes not just from the incredible stories of the ancient Vedic texts, but is also carved in stone throughout the Hindu world. The megalithic Kailasa Temple dedicated to Lord Shiva is carved from a single rock cliff, and it is said that it took just 18 years to chisel out the estimated 400,000 tons of rock excavated in its construction. But how was this accomplished over a thousand years ago when modern engineers say such a feat is not even possible with today's technology?

The Alien Disks

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.

Return to Gobekli Tepe

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?
