what if that cause was natural? while the definition of god is dynamic, most people would agree that when they think of god, they think supernatural. so, if the cause(assuming there was one) was natural, than who's to say it was god? you know, if there is a god, you probably have no better an idea of what it/he/she/other is than anyone else. that's what i reject more than anything else, that people who have never actually spoken to god, or any such thing, actually think they know what this god is like. let alone the fact that there is no evidence, as far as we know, that there is even a god to begin with.
and yeah, freethinker, the funny part is that there are people who basically believe what i said. and yeah, it would be pointless for such a god to exact retribution for anything. but like most atheists say, we don't necessarily reject the idea of a god in general, most of us reject the theistic gods, cause those gods are just ridiculous.
