: A massive comet or fleet of comets struck or exploded over North America around 12,900 years ago, an occurrence the authors simply call "the Event".
: This catastrophe is cited as the primary cause for the sudden disappearance of North American megafauna, such as mammoths and saber-toothed tigers, as well as the collapse of the Paleo-Indian Clovis culture.

In the book , authors Richard Firestone, Allen West, and Simon Warwick-Smith argue that a prehistoric cosmic event approximately 13,000 years ago triggered the end of the last Ice Age and caused mass extinctions. They propose that a large comet fragmented in Earth's atmosphere, leading to global fires, floods, and sudden climate shifts. Key Claims and Findings
