A World Still Molten

You could not stand here: the ground is still liquid rock. The young Earth is a furnace, struck again and again by the rubble of a half-built solar system. Then something the size of a planet hits it, and the splash thrown into the sky cools, slowly, into the Moon. The surface hardens. Rain falls for an age and does not stop, and the first oceans gather, warm and dark. And somewhere in that black water, something is about to happen that has happened nowhere else we have ever looked.
