Your brain is evidence. You think it's more reasonable to believe that it evolved from some unknown self replicating molecule.
Since there's a literal planet-full of evidence to support evolution, I'd rather side with that which is irrefutable rather than just assume the God of the Gaps because I can't explain something.
Or, even worse, use the argument from complexity.
If you're about to say that the brain is far too complex to have evolved through natural selection, I'm going to reply that god would have to be infinitely more complex than the human brain which only leads to the god-defeating conclusion that god must then also have been created.
You fail. Repeatedly. Pretty sure that you have no fucking clue what you're talking about. Cells divide. Molecules don't "divide" lol.
