The Megatsunami That Almost Ended Life on Earth

Some of the greatest turning points in Earth's history were never witnessed, yet they remain written into stone for anyone patient enough to read them. 🌍 More than three billion years ago, our planet experienced the largest known Megatsunami in Earth's history. Triggered by an enormous asteroid impact, this ancient catastrophe vaporized part of the ocean, darkened the skies across the globe, and came closer than almost any other known event to ending life on Earth. But the story preserved inside some of the oldest rocks on the planet reveals something even more unexpected. Using the latest scientific research from the Barberton Greenstone Belt in South Africa, this documentary explores how the massive S2 impact reshaped the Paleoarchean world. Discover the evidence hidden within ancient spherule layers, the giant waves that crossed a nearly ocean-covered Earth, the chemistry that transformed the seas, and the surprising reason life not only survived, but flourished after one of the most violent events our planet has ever experienced.
