someone who does not believe in any gods. there are two kinds of atheists: strong atheists believe that the existence of gods are impossible, weak atheists (called agnostic
s) don't believe in god, but would start believing in him if he were proven true.
atheists usually come in two flavors: atheists who don't believe in god based on science, evolution, the big bang, humanism, skepticism and logic. the second group, unfortunately, are goths and vampires who don't believe in god because it's "alternative" and "anti-establishment".
