societal environment

I live in the deep south, atheism is not only not socially acceptable here, it wasn't even understood throughout my childhood. Nobody would say "wow not believing in god is evil you're a bad person you're going to hell" they'd say "what? you dont believe in god? that doesnt even make any sense, ive never heard of that"

None of this made it "common sense" to believe in any gods. Common sense remains that believing in things without evidence is foolish.
