Last month the mystery deepened when a team of Italian scientists said they found a vast city stretching thousands of feet below the Egyptian structures. Using ground-penetrating radar, the scientists reportedly detected massive shafts and chambers hidden beneath the Khafre Pyramid. The controversial research, not yet peer-reviewed or published in a scientific journal, has reignited a fringe theory that a now-lost civilization may have had a hand in building or inspiring the pyramids. Alternate historians like Graham Hancock, a frequent guest on Joe Rogan's podcast, have long posited that a highly advanced prehistoric society was wiped out by a global cataclysm, possibly caused by a comet impact, around 12,800 years ago.
