Something Was Here Before Us... And Scientists Are Terrified

Could we really be the first advanced civilization on Earth, or just the latest? In this relaxing Science for Sleep documentary, we explore the idea that intelligent societies may have existed millions of years ago and disappeared without leaving obvious traces. From strange geological clues to ancient stories that hint at lost knowledge, we examine the evidence and the mystery behind it all. Learn about the Silurian hypothesis, subtle climate markers, and how entire civilizations could rise and fall without a clear record. Is it science, speculation, or something in between? Sit back, relax, and let your mind wander through one of the most fascinating possibilities about our planet’s past. Topics covered: Silurian Hypothesis, previous civilizations on Earth, Paleocene Eocene Thermal Maximum PETM, Gobekli Tepe archaeology, Younger Dryas impact hypothesis, mass extinction events, geological record, deep time, lost civilizations science, Adam Frank Gavin Schmidt paper, technosignatures, Anthropocene epoch, fossil record limits, planetary geology, ancient climate change
