UPDATE: to be clearer, evidence like observations not philosophical arguments. no sensory input will make my a mystic. there are no faeries. even if we discover small pink winged things we name fairies. there is no God, even if we find some guy who ruins our ideas of physics, and call him god.
and no i'm not just being stubborn in the face of proof atheism is crap. the notions of God and faeries contain untestable bad (and by bad, i mean unspeakably horrific) explanations. when atheists say there is no god, (at least sane ones), it means the one that can't be criticised by any possible observation. and thanks to this shield, can't be confirmed either. he's just silly, like the invisible, ethereal (yet able to push) angel explanation of gravity.
