How Ancient Humans Survived Mega-Floods Without Technology

How did ancient humans survive apocalyptic mega-floods thousands of years ago without modern technology, dams, or concrete? Long before heavy machinery or digital weather tracking, ancient civilizations engineered brilliant flood-defense networks that diverted raging rivers, elevated entire cities, and predicted catastrophic floods weeks before they struck. _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- In this documentary, NEXA uncovers the lost hydraulic engineering of: • Ancient China: How Yu the Great diverted the Yellow River using massive canal systems. • Indus Valley (Mohenjo-Daro): Elevated city platforms and advanced underground drainage. • Prehistoric Europe: Raised wooden stilt villages known as Palafittes. • The Amazon Basin: Massive artificial earthmounds (Lomas) built to withstand monsoon deluges in Llanos de Moxos. Discover how simple physics, gravity, and nature-tuned architecture solved the greatest natural disasters in human history. #AncientHistory #Documentary #NEXA #Engineering #History #AncientTechnology
