How is the necrophile gang stealing Jesus' body from a tomb guarded by Roman soldiers more plausible than Jesus resurrecting? Ever heard of Occam's Razor?

Paul's conversion is documented in his own writings and the New Testament, which indicate a rational and coherent thought process. There is no evidence that he was mentally ill.

There were many witnesses to who claimed to have seen the risen Jesus. The vast majority of historians accept as fact that the disciples believed Jesus had appeared to them, which led to their bold proclamations that He had risen from the dead. It would be a far greater miracle for entire groups of people in different mental states to undergo shared hallucinations on different occasions, in different places, and for different reasons.
