Since the modesty argument requires rational correspondents, creationists are counted out! What I mean is that a creationist does not disagree with me on a matter of simple fact, in that his or her reasons for disagreeing are not themselves based on simple facts, as my reasons for disagreeing with him or her are. This makes our disagreement asymmetric. And Aumann's theorem can't apply, because even if the creationist knows what I know, he or she can't agree; and vice versa. But I think our disagreement is honest, all the same.
