In 2018, two NASA affiliated scientists proposed a wild idea, the Silurian hypothesis. It asks if a non-human industrial civilization existed millions of years ago. Would we even know sounds like science fiction? Here's the twist. Earth's crust is constantly recycled, ocean swallow, land erosion, wipeped cities, clean fossils rare. After a few million years, nearly all evidence vanishes. So instead of buildings, we'd have to look for geochemical fingerprints, spikes, and co two levels synthetic compounds. Radioactive isotopes like plutonium 200 and 44. Events like the Paleocene Eocene Thermal Maximum mimic industrial era warming, but are they natural? Ironically, a civilization that lasted long and lived sustainably might leave no trace at all. The scientists doubt any past industry existed, but they ask a deeper question. Would we even recognize the signs if it had? Maybe we're not the first, just the first to remember.
