Across the immense corridors of deep time, Earth has witnessed the rise and fall of continents, oceans, and entire ecosystems — yet we assume our civilization is the first to have reached complexity. Scientists are now asking, with genuine rigor, whether the geological record could have erased all traces of a prior advanced civilization so completely that our absence of evidence would tell us nothing at all. The question is less about ancient mysteries than about the hard limits of human knowledge itself — and what it means to search for intelligence, past or present, on any world.
