History Channel Alien Season 1

To many who see them, the legacies of the ancients are beyond understanding: Strange creatures, exotic spirits, mysterious gods, architectural marvels. Researchers still debate their origin and meaning. They appear unearthly, alien, leading some to believe the knowledge of the ancients arrived from another world. What strange forces were at work here? Did alien gods instruct our ancestors or is there another explanation hidden in history? Other clues, strewn through human antiquity, may yet reveal the real ancient astronauts.

Part 3 of a special 4 part mini season. The hunt for alien life continues in Zimbabwe, where Josh interviews witnesses from one of the largest UFO sightings in modern history. Then, in England, he investigates the infamous case that has become known as "Europe's Roswell."
