Ok, so who took him up on that offer? Who went around and confirmed what he said was true? Let alone just someone else confirming that they went there, confirmed there were witnesses and spoke to those witnesses, can you provide those actual witness testimonies themselves? Can we cross-reference that what Paul says he thinks they would say to what they themselves actually say they saw?

So, presumably being an atheist who hasn't "thought about the difference between evidence and proof," can you explain to me how just the evidence that Paul said "hundreds of witnesses" provide proof that there were hundreds of credible witness, let alone who all confirm what Paul claims?
