More than just being a magic miracle man from a virgin's loins, what's the point of the crucifixion and resurrection when it's not really death and suffering at all? A few hours of agony, followed by a long nap and then a 40 day vacation doesn't sound like a big deal to me...
So to take your point one step further OP, if someone today could do all that stuff, and really had all of these powers and abilities, what's the worst that we could do to them? Electrocution? Waterboarding? Hanging? Firing Squad?
In each of those methods I can see how a resurrection even could take place, since the body is still intact.
Why not ask how a Jesus figure would survive 18th Century French executions?
If you really want to see something cool, let's have our mythological figure get back up after execution via guillotine!
