Published in 2002, 'Underworld' is a substantial book by Graham Hancock, spanning approximately 1,000 pages with 2,000 footnotes. It documents the author's seven years of scuba diving expeditions with his wife, exploring submerged ancient structures. The book presents evidence for advanced civilizations that existed during the last Ice Age and were subsequently submerged by rising sea levels, challenging conventional archaeological timelines. It was written with a defensive approach, anticipating criticism for its controversial claims.
