Scientific evidence does not support the claim that cataclysmic events occur in regular 12,000-year intervals, as geological and climatic data point to complex, multiscale forcing mechanisms rather than periodic global catastrophes.
The claim proposes a strict, periodic cycle of global cataclysms occurring every 12,000 years. While certain historical events like the Younger Dryas boundary have been debated around the 12,000-year mark, comprehensive geological, impact, and paleoclimate studies show no evidence of a regular, repeating 12,000-year cycle of planetary cataclysms. The literature points instead to complex orbital, tectonic, and climatic drivers operating across vastly different and irregular timescales.
