That's stupid, those are contemporary expressions. We need to think back through history a little. Hmmm...... religion has been a part of humanity since the dawn of man, so perhaps "God" is the most word used ever simply due to the fact that the idea of a deity is so ancient, but obviously, each language has a word for it. So lets just say God.
Before bạn call me a theist pain in the đít, mông, ass hoặc whatever, I actually don't believe in a God, I am just sayin, God is a pretty old word.
