A chilling new theory has emerged surrounding the mystery of a city hidden beneath Egypt’s iconic Pyramids of Giza.

Italian scientists recently used ground-penetrating radar to uncover massive shafts and chambers stretching beneath the Khafre Pyramid, suggesting the existence of a vast underground city.

This discovery has reignited fringe theories about a lost, highly advanced civilisation, possibly wiped out by a global cataclysm, such as a comet impact around 12,800 years ago.

Prominent geologists are now supporting these claims with evidence of catastrophic flooding, adding more intrigue to the ancient mysteries of Egypt.
