: Some scientists argue that the evidence, such as the "black mats," can be explained by natural environmental changes rather than a comet. Others point out the lack of a clear, single impact crater from this specific timeframe.
: More recent studies have found similar geochemical signals (like high platinum and iridium levels) at dozens of sites worldwide, keeping the debate active in the scientific community.
: The authors connect scientific data to global oral traditions, suggesting that ancient legends of worldwide floods and "Thunderbirds" are actually eyewitness accounts of these cosmic impacts. The Cycle of Cosmic Catastrophes: How a Stone-A...
While many readers find the narrative compelling, the "Younger Dryas Impact Hypothesis" remains controversial.
The Cycle of Cosmic Catastrophes: How a Stone-Age Comet Changed the Course of World Culture : Some scientists argue that the evidence, such
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
: The book suggests Earth is subject to a recurring cycle of catastrophes and that we may be entering a new period of increased danger from space. Scientific Evidence Presented : The authors connect scientific data to global
: 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".
