Graham Hancock

Graham Bruce Hancock 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.
