When I was writing about the Muslim apologetics, pretty much all the arguments kept coming back to the fine tuning argument. Basically, this argument says that if some fundamental parameters of the universe were different, the world wouldn't look the way it does and we would not exist in our current forms. Creationists extrapolate from that to the idea that therefore the parameters must have been specifically set that way by some intelligent, conscious entity in order to generate a universe that can house us. Then they generally then make a wild leap to assuming that this hypothesised intelligent, conscious entity still watches us, meddles in the world, wants a relationship with us and cares deeply about how and when we have sex.
