The "Silurian" Hypothesis: Was There A Civilization Before Us? | History For Sleep

The "Silurian" Hypothesis: Was There A Civilization Before Us? | History For Sleep What if another civilization existed millions of years ago—would we even know? Earth is 4.5 billion years old. Humans have been industrial for 200 years. That's 200 years out of 4.5 billion. In 2018, two scientists asked a startling question: How would we detect an ancient industrial civilization in the geological record? Not aliens or reptile people—just the idea. If something built cities and burned fuel 100 million years ago, what would survive? Cities crumble, roads erode, even plastic breaks down. Continental drift shuffles everything. Subduction zones swallow entire regions. This episode of Sleepy Secrets of History explores the Silurian Hypothesis, why fossilization is incredibly rare, and what chemical traces might remain in rocks after deep time erases everything else. Watch to learn why we can't rule out ancient civilizations, discover what temperature spikes and carbon isotopes reveal, and understand why this matters for finding alien life on other planets. Perfect for anyone fascinated by deep time, geology, and the limits of what we can know about Earth's past.
