Alien Life & The Silurian Hypothesis

Alien Life & The Silurian Hypothesis Subscribe to Science Time: https://www.youtube.com/sciencetime24 #science #shorts #space The Silurian Hypothesis posits a tantalizing question: Could an advanced civilization have existed on Earth millions of years ago, leaving virtually no trace? Named after fictional aliens from "Doctor Who," this hypothesis doesn't claim ancient lizard people once ruled the planet. Instead, it's a thought experiment used by scientists to explore how we might detect signs of ancient civilizations on other planets. The clues could be as subtle as heightened carbon in the atmosphere or microscopic plastic shards in sediment. While the idea of a pre-human advanced civilization is pure fiction, the Silurian Hypothesis opens intriguing avenues for astrobiological exploration and the study of Earth's deep history.
