If God/gods is true to many, does it mean it is real? Is truth always conniving with reality or both have separate businesses in the human mind?
If someone says to me the word Centaur I have a semiotic notion of the symbolic value of the word, I know the word exists and I know what it describes, but does not mean there is a half man, half horse creature doing his shopping and living a happy and productive life.
Likewise the concept or idea of a god(s) can be real while in no way implying the existence of actual god(s).
