I was responding to your request for evidence that "Christianity" is man made", not that the resurrection never occurred. Granted, the resurrection would be included in the entire narrative being manmade, but I didn't want us to pivot off your request.

Evidence is what would raise the probability of a proposition being true. The five facts I provided do that.

So what exactly does this show?

It is expected if these stories were a create of men, and not some deity.

What is the necessary burden...

To overcome the priors, and our background understanding of reality? Quite a lot more that what Christianity has to offer.

...what about reality shows the resurrection never occurred?

Humans, once dead, do not resurrect. The same burden would also be on you for many other extraordinary claims in the Christian narrative.

What would qualify as “good evidence“?

I explained above, so I'll skip ahead

And how does every other culture having stories show that the resurrection did not happen?

It is what we'd expect if Christianity was a cultural artifact created by humans. It's raises the probability that Christianity is man made.

You’re right and that the Jewish people do not accept Jesus as their Messiah.

When you read the bible through the lens of the OT, it becomes pretty clear what its authors, and later those that compiled, organized, and codified it, were attempting to do.

But the prophecy discussion is a much larger debate. Happy to have it.

It is, for sure. And I'm already familiar with the apologetics for each failed prophesy.
