I have no idea. I've never polled atheists. My guess is that atheists would probably not be receptive to God-based explanations for ordinary phenomena, but that doesn't mean they accept Darwinian evolution either.
Trofim Lysenko was a famous atheist "scientist" who ran all biological research in the Soviet Union. Not only did he reject Darwinian evolution, he sent supporters of Darwinian evolution to the GULAG system of concentration camps. So it isn't that clear cut.
Yet you agreed that atheists are largely evolutionists.
Do you think it might be the only other choice?
