Depends what kind of god it ends up being like. If it’s one of the earlier versions of God where He’s all cruel and sends you to Hell because you exist, then fuck em.
But if He’s more a loving god who wants you to enjoy your life, that would be cool having a god like that.
Of course, whatever the god in question was like, if he appeared before me, no matter what I say I’d prolly be shakin in my boots and would do whatever the hell he said. I mean, seriously, imagine having a god pop up in front yo ass goin, sup homey? Could the human mind even handle it? If God exists, perhaps this is why He won’t physically show Himself to peeps, you gotta wait till you pass on and achieve a greater form of existence or something.
But eh. I suppose if God was proven to all, the world and its people would change quite a lot. I imagine that most people would behave as said god wanted, so the world could be a lot of different things, depending on how cool the god is, or how much of an ass he is.
Other than complete and utter fear, not sure how much I would change. He made me how I am, so if He doesn’t like it, let Him think about it twice next time He creates a state of existence.
