I think you have it backwards. Those who believe in fantastic stories having to do with the supernatural are the ones who bear the burden of providing a lot of credible evidence before the claims are even taken seriously. When somebody tells me that there was a person who could do this or that kind of miracle, I automatically assume that the claim is bunk, and so should any rational person. If significant amounts of strong credible evidence emerges for the claim, then it should be examined to see if there are any other reasonable explanations.
Christianity, in my opinion, hasn't gotten to this point yet. All we have are ancient stories written many years after the supposed supernatural events occured. There are also a few extrabiblical, non-christian early references to Christians and the object of their worship. This is nowhere near enough evidence to believe in the literal truth of the Christian story, in my opinion.
