Episode 1

Aliens and the Old West

44m8.0 / 10

Ancient Astronaut theorists believe aliens have been visiting earth for thousands of years. If so, might we find evidence of this even in the stories of America's Old West? In Aurora, Texas, the local cemetery claims to hold the body of an alien whose ship crashed there in 1897. In Utah, petroglyphs depict strange beings wearing what look like space suits. In southern California, 19th century ranchers reported seeing an otherworldly creature emerge from Elizabeth Lake. And even in Tombstone, Arizona, the home of Wyatt Earp and the site of the gunfight at the O.K. Corral, cowboys claimed to have shot at a giant, metallic bird Are these simply campfire tales, or did the cowboys and native people of America's Wild West actually come in contact with alien beings from another - much more distant - frontier?
