In what way is the Resurrection the best explanation?

[Pat Mustard]

The resurrection is the best explanation for the rise of the early church, with the belief set they had.

No it isn't. Many religions, including I suspect christianity, grew out of a con game. And the best exemplar of this particular beginnings for christianity is Saul of Tarsus. He clearly weaves a fantastical and improbable story simply to gain power and followers for himself (a kind of classical Roman Jim Jones if you will).

And there are many other explanations which are far more plausible and valid than a physically impossible "Yeesus came back to loife, goysh!"
