The Sherman, you persist in misunderstanding what an atheist is.
In general your idea that you can be an atheist while allowing the possibilty of a God is like saying that you don't believe in Santa while allowing the possibility that your Christmas presents might have been delivered down the chimney by a nice chap in a white beard and a red cloak.
This is what we have:
A theist is one who believes wholeheartedly in God.
An agnostic is one who does not so believe but admits that God might exist.
These two are so related in their acceptance of the possibility of a supernatural being that they are very close; they sit next to each other, cheek-by-jowl, on the intellectual bench.
A million miles away, across an intellectual gulf, is the atheist , who firmly, unequivocally, unreservedly, categorically dismisses the idea of God as absurd. He may one day, by some sort of celestian decree, be proved wrong, but that is what he is.
Since, The Sherman, you obviously do not belong to this latter category you are not, by definition, an atheist.
You are just not qualified to belong to our club.
I cannot explain it any more clearly than that.
