You mean the whole thing. That no one is saying, "evolution is a fact, therefore God doesn't exist." When I asked, 'which part?' I was asking which part of those two assertions, as it seems like both are said often, separately.
Together, it isn't said that way. Perhaps it is, but not sure if I can find it. Instead what is said, I think, is in vein of 'evolution doesn't need a supernatural agent (like God) to explain its process.'
I'm sure many, if not all proponents of TOE, would concede that. That is not same thing as was said earlier. And is more or less an unwritten rule of scientific explanation of the materialistic variety. I'm sure many think I can find that, though not up for searching for it right now (or anytime real soon) as I really think that is common argument.
I do also think some, but not most, will say the above 'doesn't need God to explain process' and then add on, 'therefore God doesn't exist.' But admittedly, I don't know if I can find that. I'll just be on lookout for it, as I think it does come up periodically from certain type (called atheists). If it doesn't come up in next next 10 days, I'll not lose any sleep over whether or not my claim here is accurate. I really do think such a claim is made, but not frequently. More like occasionally.
