So I misunderstood the person I was replying to. I thought he was saying that supernatural was outside of evidence; but he meant more specifically empiricism; which literally means sensory data, but probably he means to extend to the sorts of repeatable physical tests. [EDIT] Christianity is certainly about belief in the unseen. My claim was simply that it was belief in the unseen based on sufficient evidence, as opposed to belief in the unseen specifically without evidence. I wouldn't expect a self-aware NPC from within World of Warcraft to be able to prove the existence of humans by doing repeated tests; by definition whatever tests he does will be mostly following the rules of the system that he's in. Such an NPC could ask for specific things to be done by an "alleged" human, which would provide evidence. Whether that sort of non-repeatable evidence counts as "empirical" in the philosophy of science, I don't know.
