Twelve thousand years ago, the world reorganized catastrophically. Temperatures in Greenland collapsed by up to 14 degrees in a single year. At least 35 species of large animals vanished from North America almost overnight. And 27 million square kilometers of coastline — the size of Africa — disappeared under 120 meters of rising ocean. What was on those coastlines when the water came is a question science has never fully closed. This video examines the Younger Dryas event, the impact hypothesis, the mystery of Göbekli Tepe, and what the submerged archaeological record may still be hiding.
