Season 14 Episode 1
Has Antarctica served as a home base for extraterrestrial visitors to Earth for thousands of years? As human exploration of the frozen continent increases, are we about to come face to face with both the ruins of an ancient advanced civilization buried under the ice–and perhaps even aliens that still inhabit the frozen continent to this day?
Piri Reis map
The map's historical importance lies in its demonstration of the extent of global exploration of the New World by approximately 1510, and in its claim to have used a map of Christopher Columbus, otherwise lost, as a source. Piri also stated that he had used ten Arab sources and four Indian maps sourced from the Portuguese. More recently, the map has been the focus of claims for the pre-modern exploration of the Antarctic coast.
