So you must determine whether something came from nothing, or everything came from something. The eternal steady state theory and all of its derivitives and distinctives have been abandoned on the asheap of atheistic history.
The other question which you would not address is first life. It is the preeminent problem for the darwinist atheist.
I think that's supposed to be a problem for any "darwinist". Atheism is supposed to be implicit in the label, and "darwinist atheist" redundant.
