I would say " Sir I am sorry that I didn't belive in you Sir"
"since your pure existence destroyed just all of my beliefs I will go aboot kill myself now"
"Hahah jus kiddin dude, well so why did you create us, I mean you are all omnipotent and stuff you know"
"Since you know everything and shite you probably know this question we got on earth, so could you create a stone that is so heavy that you can't lift it?"
"Anotherthing, why the **** did you bang some earthwoman? I mean well I don't see the point, and this bible thing, why is it so ****ed up"
"Oh wait, before you answer any of this, do I have any chance to go to heaven? You could show me around a little. Oh yes if I can'T then **** you and the Horse you rode in on, if not well then forget aboot that."
Well probably a lot more you know, he's the DUDe (if he exists that is)
