8 Theories That Suggest We're NOT The First Civilization On Earth

Two real scientists — a NASA climate director and an astrophysicist — asked a question that should not have a serious answer: if an industrial civilization existed on Earth millions of years before us, could we even find it? The terrifying part is that the planet erases almost everything it once carried, and the only trace a lost civilization would leave isn't ruins — it's chemistry buried in the rock. From a natural nuclear reactor that ran two billion years ago to the thin, glowing layer we're pressing into the stone right now, this is the unsettling case that we might not be the first here — and definitely won't be the last to vanish.
