There is evidence, albeit non-conclusive, but you ignore it because it doesn't fit your world-view. For one thing, he was said to have appeared to approximately 200 people on one occasion, most of whom were still alive when Paul wrote about it
You sell yourself short. It was actually 500. It doesn’t matter though because it is just a made up number.
Anyway, 600 people people saw me scale the Eiffel Tower on the outside yesterday, also the Thirteen, Rocky and Jim the brother of Bod.
You must believe me since I’ve got more witnesses than you have for the resurrection of Christ.
- the point being "if you don't believe me, go and ask them!".
How? Paul doesn’t tell us who any of them are.
There is also the fact that the apostles were willing to die for their belief - they'd hardly have been willing if they knew it to be false.
But they die for their beliefs in the same stories that Jesus is resurrected.
A lot of people sacrificed their lives to stop Voldemort. They’d hardly have done that if he was fictional.
