What If the First Earth Civilization Was NOT Us? | Great Filter Hypothesis
Two billion years ago, deep in what is now Africa, nuclear reactors switched on by themselves and ran for hundreds of thousands of years, splitting atoms with the precision of modern technology. But humans wouldn't exist for another two billion years. We're about to journey through evidence that might shatter everything you think you know about Earth's history. We'll explore ancient isotopes that don't belong, mass extinctions too fast for nature, and the terrifying possibility that advanced civilizations have risen and fallen long before we ever existed. We'll dive into the Great Filter hypothesis and ask the ultimate question - are we Earth's first intelligent species, or simply the latest in a long line of forgotten worlds?
