As others have said...if the existence of this god also meant that worshiping him meant the difference between eternal peace or eternal torture...then of course I would worship him. Eternal peace (I mean real peace, not oppressive peace, which is what heaven is implied to be) is worth any sacrifice. Its easy to think of defying authority and experiencing torture for a limited time until death, but I find eternal torture and pain that never gets easier to be a different matter entirely.

If, on the other hand, it does not. Then I would be interested in talking to him about the universe's mysteries, but not moral debates.
