The earth gave itself day and night, tilted itself so that we get seasons. Without the magnetic poles man would be unable to navigate the trackless oceans of water and air, but they just grew there.
How about the sugar thermostat in the pancreas? It maintains a level of sugar in the blood sufficient for energy. Without it, all of us would fall into a coma and die. Why does snow sit on mountain tops waiting for the warm spring sun to melt it at just the right time for the young crops in farms below to drink? A very lovely accident.

Who gave the human tongue flexibility to form words, and a brain to understand them, but denied it to all other animals? Who showed a womb how to take the love of two persons and keep spliting a tiny ovum until, in time, a baby would have the proper number of fingers, eyes, and ears in the right places, and come into the world when it is strong enough to sustain life?
There is no God?
