I don't feel like arguing about priors - good evidence will overwhelm ordinary priors in many circumstances - but in a story like the one he told, each of the following needs to be demonstrated:

1. God exists.
2. God created the universe.
3. God prefers not to violate natural laws.
4. The stories about people seeing angels are based on real events.
5. The angels seen during these events were actually just robots.
6. The angels seen during these events were wielding laser turrets.

Claims 4-6 are historical, and at best it is difficult to establish 99% confidence in that field for anything prior to - I think - the twentieth century. I don't even think people have 99% confidence in the current best-guess location of the podium where the Gettysburg Address was delivered. Even spotting him 1-3 the claim is overconfident, and that was what I meant when I gave my response.

But yes - I'm not good at arguing.
