Having been an atheist evolutionist I know that no argument will change that opinion. But I changed.
The Bible even says that if your dead close relative comes back from the dead and warns you to believe, you will still not believe. Belief in the "foolishness" of the gospel does not happen because of a natural process of hearing both sides and concluding that the biblical answer makes the most sense.
If any of my dead relatives came knocking on my door, I would instantly become a hard core true believer. There would be the proof I've been waiting all my life to see. I would almost certainly still believe in evolution, too, due to the accumulated evidence. I would not neatly fit into anyone's rigid doctrine, nor would I necessarily align myself with any organized religion. I doubt I would go to church, either. But, you show me enough convincing proof of the right type and you get a convert. No proof, no convert.
I'm guessing he's agnostic. If God shows himself to him, he'll believe.

You got that right. Fortunately, I Know logic is God's creation, so that made my decision about the gospels rather easy.
