Hey Robert,
"God" has never been my stronghold nor my favorite topic. The reason is quite simple, I do not believe in "God." So receiving the idea of a or the "God" might be coexisting with our minds or brains is rather overwhelming.
To me, the term "God" is used as a scapegoat for any miseries and or problems we have; the reason why we believe in "God" is because we do not believe in ourselves and need that symbolic person to blame on. I think the reason why we always refer to "God" is that it's such a good catch phrase, e.g. "Oh my God!"
I guess the idea of "God" do increase our chances of survivability
slightly, e.g. One can sing "God" related songs at a cathedral or church with many fellow friends, the soothing sound of the music is an enlightenment to many, and subsequently he/she can talked to those people about any problems they have. It cancels out all anger and hatred in one and perhaps can prolong life
slightly.
I hope I did not offend any religious members/visitors, if I did, then I apologize deeply.
Best regards
Zelta
