It sounds as though you are talking about the difference between surviving the Crucifixion and being Resurrected from the dead.
I am fully convinced that Jesus lived for many years after the Crucifixion.
Jesus himself told people that he was alive, and not a ghost. I think what you will have difficulty with is proving that Jesus is God - at least any more than anybody else is.

P.S. Here is an example of logical analysis of the Bible testimony. I might go through the account about the Crucifixion but I do not agree with Robert Graves point by point:
