When Earth Lost Its Giants: The Catastrophe That Ended the Ice Age | Documentary For Sleep

Twelve thousand years ago, you could walk from London to Amsterdam across dry land. Woolly mammoths, saber-toothed cats, and giant ground sloths ruled the continents. Then within a single human lifetime, it all vanished. The ice melted catastrophically. Seas rose 400 feet. Thirty-five types of giant mammals went extinct. The climate reversed so violently scientists thought their data was broken. Was it gradual warming, or did something from space trigger the greatest catastrophe in recent Earth history? This video examines the evidence for the Younger Dryas Impact Hypothesis, the megafloods that reshaped continents, the flood myths that might be memories, and what our ancestors survived to build the world we inherited.
