More precisely, the Christian Church would never exist if Jesus had never risen. Nobody would have ever heard of Him. You claim essentially that Paul took up the "myth" and ran with it to spread his own franchise, but that franchise never would have taken off either had the story never happened.
There are too many examples to debunk this it is not worth addressing.
Why if Jesus was a historical figure does Paul never talk about a historical Jesus? Why does he not mention anything that is in the gospels?
Facts don't lie or have an agenda. Facts are just facts
"God did it" is not an argument. It is an excuse for intellectual laziness.
If your viewpoint has merits and facts to back it up why would you have to lie?
