There are too many assumptions in your statement. You presuppose that what exists is created by a super-entity or personal GOD and yet that may not be the case at all. You can't even prove that GOD is an individual person or a disembodied mind..etc. We don't know if there is a GOD and we don't know what or who he is, assuming he exists.
If there is a necessary or non-contingent reality behind this material world, that caused this universe to exist with all of its laws.etc, that doesn't imply that it resembles the Christian, biblical deity.
Maybe the future is causing or at least influencing the past from God's perspective and God Himself is a person only when persons are created through a natural process within the space-time continuum. So in a way, the GOD PERSON or SUPER-ENTITY, emerges in the future, when a trillion-trillion minds unite as ONE, then what emerges from that union is GOD THE PERSON. Now what exists, within space and time, isn't a divine, individual SUPER-ENTITY, but rather a God that is evolving, unfolding, growing, expanding..etc. We are part of that GOD.
As I expressed in one of my previous posts, that would be a form of pantheism. All of the potential and whatever is actualized of that potential is GOD. GOD is EVERYTHING, EXISTENCE ITSELF. That which actually IS, IS GOD. God is the state of being alive and existing. God is the potential behind the actual as well, so God is both the potential and the actual. In the future maybe God will be the SUPER-ENTITY and person but that is far from the Christian idea about God. Silly, shallow Christian theology asserts that God was in the past, "before" the universe, as a fully evolved person with Jesus, and the Holy Spirit, playing cards or something.
God wasn't a creator or a king of a kingdom, he was just a father, and Jesus was the son and the spirit was just there with them. It's just primitive, silly mythology. What I just said about a possible God is more scientific. The natural precedes the spiritual. The natural world comes before the spiritual world. Before the physical, there is only potential. A power and system of principles, that are necessary or a so called "brute fact". That simple, necessary deity isn't necessarily a person in the Christian sense, but simply a type of divine nervous system.
My body right now is functioning, and it will continue to function even if I'm asleep and unconscious. My heart beats, my liver and kidneys are functioning, and my hair and nails are growing. I don't have to be a person or conscious for that to happen. So maybe GOD, in the beginning, is just a type of divine nervous system. God exists, but not as a person in the Christian sense. In order for the divine person to exist there has to be a process of natural creation and evolution ("natural selection"), within the parameters of the laws of physics/natural laws and the space-time continuum. Nature precedes the existence of the conscious Spirit or divine personhood of GOD.
GOD THE PERSON emerges in the future, from a body of trillions upon trillions of minds united in selfless love. God is the alpha and omega. The alpha is simple, the omega is complex. God is both the simple alpha point and the complex omega point. In both points of existence there is no space or time. Space and time only exists in the process from one point to another. God is essentially EVERYTHING, and God the person is pulling the past to Himself, that it may become actualized in the "omega-point-complex" or in the complex point of omega.
All of the above is just speculation. I don't know if it is true, hence I don't really affirm or even believe it, but a part of me says "maybe that's possible". So unlike Christians who can tell you what color tie God wears and whether he likes his eggs sunny side up or scrambled for breakfast, I don't have that level of understanding and the claim that they do, on the basis of their "bible book" is just absurd. I'm an atheist because I don't have enough information to conclude anything about God. What I just wrote above about GOD is just my imagination. I don't know if it is true. It's just a mere "suspicion" (no verdict). The case is thrown out of court. Not enough evidence. Interesting but, no verdict, no conviction, hence I'm an atheist.
