"But do these conditions alone make life?"
If you have IDENTICAL conditions on 2 planets (damn near impossible I know) you will have IDENTICAL outcomes. Experiments must be repeatable to be verified.
I am not suggesting that God does not exist. I have absolutely no way of knowing one way or the other. I am saying that I believe in a physical universe whos laws determine the outcomes of all events. So I suppose you would call me a materialist.
