Since there can be nothing outside of God, the creation forms the body of God, who appears in a person - the Primal Person - Adam Kadamon who has the body inclusive of all dimensions, including material dimension. I have tried to explain the existence of different types of angels as beings created by God in the various dimensions of creation which are the different organs of the Adam Kadamon. Just as we have an infinite series of life forms on earth from Amoebae to Man in the material kingdom, we should expect infinite variations life forms in other dimensions. This will explain the various forms of angels. Just as man is a being who is created with Divine dimension within, I presume that there are angelic beings with similar or more complex Divine dimensional existence in all other planes. These are therefore Sons of God. Sons of God reflect God and are beings with free will, which will explain the fall of the Angels and introduces the Demonology as part of Angelology
