The fossil record tells a story of catastrophic discontinuity, not gradual change. Mass extinction events have wiped out half to ninety percent of all species multiple times in Earth's history, reshaping life on a planetary scale. That pattern, once dismissed as heresy against uniformitarianism, is now scientific consensus. The question he's raising is whether human civilization follows the same rule. Cultures rise, flourish, and then collapse abruptly, often with no clear internal cause. The archaeological record shows civilizations that simply vanish or contract violently within a generation or two. If natural systems are governed by catastrophic resets, why would human systems be exempt? Climate shifts, cosmic events, geological upheavals: these forces don't negotiate. Societies that couldn't adapt, that lacked resilience or foreknowledge, were erased. The pattern repeats. Understanding that isn't fatalism. It's pattern recognition.
