Because discussions about the origin of both the Universe and life tend to go round in circles, I prefer these days to focus minds on the timescales involved, particularly the imense span of time required to create the elements essential for life.
Then I ask the question - does this look like a natural process or one put in place by some ('all powerful') deity with the purpose of creating life? For me it has to be the former because I can't conceive of any conscious entity going about the task in that way.
A lot of assumptions are there; even if the distances and rates are correctly identified, that doesn't mean that was how long things have been in play; that is the question; we can look at things now and assume this is how its always been, but that is a huge assumption. We cannot say how it started, what the starting point looked like, or anything of that nature, and this is the same issue with biology, too; this is what we see now, extrapolating backward suggesting is with the current things we do know now can allow to know how it all started with the current information. One of the main reasons for that is the information within systems driving all of the processes; instructions that direct processes start and stop in complex functional systems are never found to crop up by chance and improve over time; the norm is a degrading of function.
