A forgotten civilization. One that existed long before the ones we know. A civilization with knowledge and technology that disappeared. Not destroyed completely… but erased over time. Floods. Disasters. War. Or maybe something else. Because if an advanced civilization once existed on Earth before us… then history isn’t as simple as we thought. And those ancient structures scattered across the planet… might not be monuments.
