Since you have already made up your mind that there is no proof, I will not waste my time giving you proof. I "see" God but that doesn't seem to help you either and since you will accept no proof, I can't cure your blindness.
Scientists don't have a clue so they choose to call it nothing. The universe is also expanding into nothing. (I think God)
I'm not sure. I just read some things lately about him saying gravity was proof that God isn't necessary so I don't know what he would call that.
And. God, when He expects something from us, must be useful. Unlike Man; thedope, is that what you mean? Unlike Man, being useful unto Himself, and immeasurably so, mysteriously He is useful to Us. Realistically we can feel HE gets everything He expected from anyone in the summation of the universe. Man is not a Devil.
