What if everything we’ve been taught about the dawn of civilization is a lie—or at least a half-truth? Picture this: more than 10,000 years ago, while the last Ice Age glaciers retreated, a sophisticated society flourished—cities of stone rising from the earth, astronomers charting the heavens, engineers bending nature to their will. Not a ragtag band of hunter-gatherers fumbling with flint, but a lost civilization rivalling Egypt or Mesopotamia, erased by time and catastrophe.
