Athe was born from the thermal energy of the big bang. That's why she's so hawt.
See, Athe demands that her followers argue against religion. She rewards her most loyal subjects in the afterlife by endlessly making wild love to them. That's why I spend so much time in the R&S section of Yahoo Answers.
It's worth noting that even gay men and straight women cannot resist the divine hawtness of Athe, so all genders and orientations are equally welcome in Atheism. We're one-up on Christianity in that regard.
