When The Sahara Was Green: Why Did It Turn To Sand? | History For Sleep Ten thousand years ago, the Sahara wasn't a desert. It was green—lush grasslands, rivers flowing, hippos in marshes, elephants walking through forests. Rock art shows people swimming where only sand exists today. Satellite imaging reveals ghost rivers buried beneath dunes. This episode of Sleepy Secrets of History explores the African Humid Period, why Earth's orbital wobble controls the Sahara's cycles, and how this disaster forced the birth of Egyptian civilization along the Nile. Watch to learn what Lake Megachad reveals about the ancient climate, discover why the Sahara turns green and back to desert every 20,000 years, and understand whether it could happen again in our lifetimes.
