Furthermore, i've seen arguments that the resurrection can be inferred from history and it really doesn't fly. Even if you had good evidence, which you don't, extraordinary claims need extraordinary evidence. By and large, the most parsimonious assertion is that the resurrection was simply a hoax. Furthermore, even if you prove absolutely that Jesus rose from the dead, it's still not parsimonious to say that he's God.
So you've got the following problems:
1) The unbiased historical evidence doesn't actually point to a literal resurrection.
2) even if it did, it's still more parsimonious to say the history was falsified.
3) Even if you believe the evidence about the "tomb being empty", It's more parsimonious to say Jesus survived the crucifixion and then woke up 3 days later.
4) Even if he rose from the dead, it doesn't prove he's God or that the christian religion is correct. I think there are contemporary records of people popping back to life after being "dead" for half an hour, maybe longer.
IMO you need to approach it from a different angle than historical perspective. ( I've thought about this a lot, but i'm still not a theist ).
1) Assume the universe is somewhat deterministic ( not necessarily entirely ), and that God planned everything.
2) Religion exists, and chrisitanity is the largest and IMO the most interesting of the bunch
3) It follows from the above that since christianity exists, God planned it.
Of course, that means you have to admit that God planned out all the other religions also, but at least you have the advantage that Christianity is the biggest game in town. (Not that this bothers me much, whenever i'm in a religious mood, I have a pretty strong universalist streak. )

On a side note, i wonder how long till people start believing in "Theistic memetics", e.g. "Religion evolves, according to God's plan"
