A question I sometimes ask myself when reading fiction set in universes where gods are known to exist, such as Terry Pratchett's Discworld* (where the gods like atheists because it gives them something to aim at...)
It helps highlight the idea that given any place where there is an absolute truth about supernature--whether it be that there is a God, that there are no gods, or that there is only a Bikini Goddess of Endless Vacations--the majority of viewpoints on the subject will be flat-out wrong.
I suppose any actually-extant deity might ask themself about atheists sometimes also, especially if they left enough pretty obvious clues for them.**
* Okay, the rules of theology are slightly different on the Disc. But still...
** Unfortunately some of the most obvious clues, such as the existence of the bikini, are taken for granted.
