In the earliest chapter of Earth's existence, the planet was not cooling quietly into stability but was instead being continuously remade by a relentless bombardment from space. New research reveals that asteroid impacts during the Hadean aeon were not merely catastrophic interruptions but the dominant source of heat shaping the young planet's crust, far outweighing the internal warmth of radioactive decay. This sustained violence was, paradoxically, the forge in which the conditions for continents — and eventually life — were slowly hammered into being. The near-absence of rocks from Earth's
