A Civilization May Have Lived on Earth Before Us, Say Scientists

What if we weren’t the first advanced civilization on Earth? Some scientists suggest that long before humans, another intelligent species may have thrived here — and vanished without leaving obvious traces. By studying geological layers, climate shifts, and mysterious signals in Earth’s history, researchers are asking bold questions: could evidence of a pre-human civilization still be hiding beneath our feet? Join us as we explore one of the most mind-bending scientific theories ever proposed.
