It is buried under as much as three miles of ice in some places, but recent satellite imagery has revealed what appear to be the tops of man-made pyramids scattered throughout the ice-covered landscape. But how is that possible? Ancient Astronaut theorists suggest that an ice-free Antarctica may have been colonized by extraterrestrials in the remote past, until a global catastrophe plunged it into the ice age. Is there a greater history on the continent than what mainstream scholars suggest? Scientists have reported strange magnetic anomalies radiating from beneath the ice, the Nazis allegedly made secret expeditions to the continent in search of a lost civilization, and government whistleblowers have come forward with claims of strange sightings. Perhaps hidden beneath the ice of this frozen continent lies the truth about our extraterrestrial origins.
