If evolution was disproven , would you renounce your belief in atheism?
I doubt. You would probably gather more evidence and look at another model or change your model to fit eidence. RTB would probably do the same

The topic was "Was Darwin wrong?"
Even if God did not heal amputees and was an all around meanie this would have nothing to do with Darwin's theory and whether it was correct. You pointing out a flaw of religion does not automatically count as evidence for Darwin's theory.
