Art Bell welcomes bestselling author Graham Hancock to discuss groundbreaking underwater archaeological discoveries that challenge the established timeline of human civilization. Hancock details two extraordinary sites off the coast of India: massive cities found in the Gulf of Cambay at 120 feet deep, carbon-dated to 9,500 years ago, roughly 4,000 years older than any known city. He describes structures with huge walls, massive foundations, and over 2,000 man-made artifacts pulled from the seabed, including pottery, jewelry, and fossilized human remains.

In southeast India, Hancock has personally dived on a large horseshoe-shaped structure submerged at 75 feet, dated by sea-level science to approximately 11,500 years ago, the same date Plato gave for the sinking of Atlantis. He also addresses the mysterious structures found 2,200 feet deep off Cuba and speculates that an underwater landslide carried them to such extreme depths.

Hancock argues that 10 million square miles of land submerged by rising sea levels at the end of the Ice Age likely hold the remains of a lost urban civilization. He suggests ancient Indian texts point to a society less focused on material technology and more oriented toward spiritual development, representing a fundamentally different path of human progress.
