Pandeism is a philosophy incorporating elements of pantheism and deism, so it is actually a kind of pantheism. Pantheism historically has several different meanings, o…ne of which is worship that admits or tolerates all gods, and another of which is the belief that God is the universe, and the universe is all there is to God. Pandeism was developed from the latter meaning. In very simple terms: Pantheism sees God being the universe and everything in it. Pandeism sees God existing before the creation of the universe, and the the universe coming out of God and being God.

They see God existing before and independently of universe. (MORE)
