what thought reasoning would lead you to deny Jesus being the son of God, but not deny that God may exist? Doesn't seem coherent to me, unless what you meant is that you deny specifically the existence this particular Bible God, but don't deny the possibility of a higher entity.
Indeed you got it, I do not believe in the biblical God. I am deist: I reject both revelation and authority as a source of religious knowledge with the conclusion that reason and observation of the natural world are sufficient to determine the existence of a single creator of the universe.
