Summary:
The book explores the possibility of a lost advanced civilization in the Americas that predates known indigenous cultures, drawing on archaeological evidence, mythological narratives, and astronomical data. It challenges the conventional timeline of human development and suggests that significant historical events, such as the Younger Dryas impact hypothesis, could have played a role in shaping early human history on the continent.
Key points:
1. Prehistoric Civilizations: Hancock suggests a technologically advanced civilization existed in America before the last Ice Age ended.
