Episode Overview
Could the remnants of ancient extraterrestrial visitors be hidden within the enigmatic monuments scattered across the globe? Strikingly similar megalithic sites appear on various continents, and the effort required to carve and transport the colossal stones used in these incredible constructions would perplex even today's technology, let alone prehistoric societies. Proponents of ancient astronaut theories propose that the monumental stones in Carnac, France, functioned as an early navigation system for ancient aerial vehicles. Meanwhile, the recently uncovered Gobekli Tepe in Turkey, dating back 12,000 years, features intricately carved pillars likened to a stone Noah's Ark. Did alien beings aid early humans in creating these mysterious edifices, and if so, what were their intended purposes?
