It’s part of a natural cycle.
You can tell based on the way stratigraphy and punctuated equilibrium align.
There’s tons of evidence suggesting that periodic pole flips (not pole reversals…pole flips are 90 degrees, not 180) occur on the same schedule as geomagnetic excursions.
That said, the cataclysm cycle produces novelty. Cataclysms are catalysts for evolution. Evolution is nature being entrepreneurial. Creation wasn’t some event from long ago; it’s an ongoing process. The cataclysm cycle is part of the great design.
