I occasionally get asked (frequently in an accusatory tone) why I, as an atheist, am so terribly interested in religious stories. I loved the mythology (however warped) in Darksiders. Some of my favorite movies and books center around Christian mythology and ideas, especially Revelation. (End of Days? Loved it! The Exorcist? Can't be beat!)
First of all, good mythology is good mythology, and angels and demons and horsemen of the apocalypse are just fantastic. (I am also terribly fond of African aboriginal creation myths.) The death, the destruction, the redemption, the salvation, the eternal struggle between good and evil- I'm a sucker for a good story.
Beyond that, I do like the idea of god. I like the idea of an all powerful being who cares for me, who is in charge of it all. I like the idea of a purpose for everyone and everything. Unfortunately, just because I find the idea appealing, doesn't make it true. The idea that I am the most fabulously beautiful woman since Helen of Troy appeals, too, but that's not reality either.
I cannot indulge an idea simply because it is appealing. I cannot let illogic and irrationality slide because I wish to. Some people clearly can, but I cannot. I can, however, indulge in a love of old stories and fanciful myths. So I do.
