It’s possible that Craig really believes these absurd arguments, but it’s unlikely. Given his many other highly misleading statements about Biblical scholarship, I think the most likely explanation is that these arguments are a tactic to avoid a debate–over the historical reliability of the gospels–which Craig knows he can’t win.
I’ll be frank: Craig’s case for the resurrection isn’t just misleading. It’s based on lies. There’s no way he seriously believes most of his “facts” are facts. Not in the sense his audience will assume he means, the sense of something that is not mere opinion and can be proven. He knows his main source of evidence for the “facts” is the gospels, and he knows he’d lose a debate on their historical reliability. And he also knows many Biblical scholars reject his “facts,” though he won’t tell his audience that if he can avoid it.
