What do ice ages, geology, crust shifts and super ancient civilizations have to do with each other? Well, when taken together, they tell the story of much, much longer timeline of technologically advanced humans. Our episode this week is with engineer and archeological researcher Mario Buildreps, who after years of research into the architecture of ancient cities, found something very strange. No matter where he looked, the northern face of ancient buildings was pointed towards Greenland. As he looked deeper and deeper into his dataset of great circle orientations, he realized something even weirder - the intersections of these structures clustered into five nodes. By correlating his findings with data from the Vostok ice sheet, the age of the ocean floor, and the layout of tectonic boundaries, he stumbled on an extraordinary theory. Not only were these structures much older than we realized - maybe ten times as old - but they told a completely new story of the geologic history of the Earth.
