What if We Weren't the First Advanced Civilization on Earth?

What if We Weren't the First Advanced Civilization on Earth? This mind-bending question, proposed by NASA Director Gavin Schmidt and astrophysicist Adam Frank, challenges everything we think we know about history!

In this deep dive, we explore the Silurian Hypothesis—the idea that a highly advanced industrial civilization could have existed millions of years ago, leaving only subtle traces in the geological record. We examine key evidence like the Paleocene–Eocene Thermal Maximum (PETM), a period of extreme global warming, and compare its chemical footprint to our modern industrial age (the Anthropocene).

Could ancient "Early Earthlings" have vanished quickly, leaving behind only strange isotopic anomalies, plastic waste, or nuclear artifacts? We also connect this to the Fermi Paradox: Do civilizations simply go extinct quickly, explaining why we find no one else? Discover the fascinating geological signatures (technosignatures) we might be overlooking. Watch to the end and share your thoughts: Are we truly the first?
