God showing up and granting all humans Wolverine's healing factor would be evidence he exists. Providing a good explanation of why he permitted disease in the first place might convince me he is not as evil as described in the Bible.
Edit: Aliens playing god would still be far more likely, but the above scenario would be evidence in favour of the god hypothesis.

There's no situation which would convince me that Christianity had a 100% probability of being true, because the idea that the entire scenario since I first encountered evidence of Christianity being true was a hallucination or that I was a Brain-in-a-Vat could never be disproved, but I can easily imagine scenarios that could make me raise my estimated probability of Christianity much higher, to 50%, 90%, perhaps higher.
If I were teleported into an alternate world where world history and the like seemed more consistent with Christianity being true, I could easily envision my probability ranking to as high as my current one for Atheism, to the point that I would act based on the assumption that it had a 100% probability.
The Second Coming? An opportunity to have a chat with the Lord Himself? An analysis of a communion wafer revealing it to, in fact, be living human flesh? It's seriously not that hard to think of these.
To apply the same reasoning the other way, if you aren't a Christian, what would be a situation which would convince you of the truth of Christianity?
