WRONG WRONG WRONG!
Atheists do not say there is no god, they simply do not happen to believe in one, they can be just as open to the idea of one as any theist & have the same capacity for leftfield thinking.
I will go out on a limb & wager that you know just as many unimaginitive theists, but simply don't notice them due to confirmation bias.
NEVER GENERALISE. Atheists are arguably the most diverse group of any kind on the planet. There are imaginitive ones, open to the idea of god & all sorts of other shit, (& unlike theists, not bound by the FEAR that belief in god induces), & there are unimaginitive atheists. Same goes with theists too, so yeah.
