Ah. I see and I'm sorry for any confusion but there was no u-turn. Both posts were just me loosely thinking out loud that given the huge amount of time evolution is talking about, the beginning of life and the following evolution here on earth is close to inevitable and not, as some others claim, impossible.
EDIT: What impresses me a great deal more than the beginning of life, is how resilient life is. Snowball Earth (1, 2 and 3??), the Permian Extinction, and life still clings on. That to me is really impressive!
