Underworld

Graham Bruce Hancock (born 2 August 1950) is a British author known for promoting pseudoscientific explanations of ancient civilisations and hypothetical lost lands. Hancock argues that an advanced society with spiritual technology thrived during the last Ice Age until comet impacts triggered the Younger Dryas about 12,900 years ago. He maintains that survivors of the disaster shared their knowledge with hunter-gatherer communities in regions such as ancient Egypt, Sumer, and Mesoamerica, sparking the earliest known civilisations. Born in Edinburgh, Hancock studied sociology at Durham University before working as a journalist for several British newspapers and magazines. His first three books examined international development, including Lords of Poverty (1989), a well-received critique of corruption in the aid system.
