Here is the Christian challenge: "I don't believe that if God appeared to us, atheists would believe. For atheists can always make the case that the appearance of God was a hallucination, or a trick by super-advanced extraterrestrials."
This bald assertion is akin to a second Christian claim that the reason atheists don't believe is because we are in conscious (or unconscious) rebellion against God, their particular God. Completely oblivious are they of the fact that they aren't in conscious (or unconscious) rebellion against Allah, or the Jewish God Adonai, or any other different God, or god, or goddess, or demon with their different (and bizarre) moral demands. Christians are narrow-atheists with regard to these other gods, so they judge them to be lacking in sufficient evidence just like wide-atheists do who reject them all. Christians themselves would scoff at the notion they are in rebellion against Allah, you see. So Christians who make this second ignorant assertion cannot be taken seriously if they also make the former ignorant one. The ignorance is one and the same.
Skepticism is a virtue anyway. I think intelligent adults should double-check their experiences to see if they comport with reality. Mature adults should question whether an experience that feels like God might be better explained as a hallucination or produced by aliens. What's wrong with doing this? Nothing I can see at all. I wish believers would do that with their own private subjective experiences, just as former believers like myself have done.
When it comes to believing despite the evidence, readers to consider that the reverse is actually the case, from what I've seen. I've seen Christians revise their faith so much in my lifetime, as the evidence shows one doctrine then another incorrect, that they would probably refuse to believe if scientists discovered the elusive Theory of Everything. They would just say God did it. So I think Christians are projecting upon atheists what they themselves would do in light of a massive amount of counter-evidence. They would still believe despite it. In fact, they already do.

Background
I've been an faithful, fully-believing, daily-praying, personal-relationship-having Catholic for about 7 years. This past Christmas, out of the blue, I wondered if anyone wrote about Jesus other than the gospels. Doing what I always do, I googled it. I was not happy. I don't want to get into this, but suffice it to say that even if there are some who mention Jesus by name and refer to followers who thought reported to have seen him after death, I was still left with an immense chasm. The gospels told me about a verbally prolific man who traveled the country side for 1-3 years, healed sickness/blindness/demonic possessions, that news spread of him throughout the land, and that in the end he caused a heck of a commotion and died on a cross. On the other hand, I have reports of a man named Jesus and verification that he had posthumous followers. No reference to any miracles, confirmation of his brilliantly wisdom-filled parables and teachings or other facts about his life? It was enough to plant significant seeds of doubt.
I recently pointed out how a high profile prayer on national TV was not answered by God. I claim this as yet another piece of evidence that God doesn't answer prayers even if he exists, which he does not. So along come the Christian wannabe apologists, and guess what, surprise...
published seven years ago, there are testimonies from former fundamentalists who became moderates, liberals, and even "ultra liberals," like Dewey Beegle, Harvey Cox, Conrad Hyers, Robert Price (who now describes himself as a "Christian atheist"), and seven others. We could add other names like Howard Van Till, Valerie Tarico, John Hick, Marcus Borg, John A. T. Robertson, James Wall, Andrew Furlong, and
