Geologically, 1 in a billion = Certain

Creationists laugh. There is only a 1 in a billion chance that could happen. The age of the Earth is 4.543 billion years. The creationist thinks it is only 6,020 years. The earth had a lot more time for improbable things to happen than the creationist imagines.
