We and everything in the universe is a dream of the Supreme Creator.
Instead of asking who is God which is answerable with a name or names which actually is an attribute or character where people is divided into subscription groups. It is best to ask what is God which is answerable with true God's nature.God is OMNIPOTENT, OMNIPRESENT, OMNISCIENT, and ETERNAL. Is your named god a God whose nature qualifies into all powerful, all knowing, all present and infinite? God made man in His likeness which means He is the source and reference of what man should and must be. God is not made in the image and likeness of man. If your god does not qualify to the four qualities of true God, then your god must be a man. You are fooled into thinking that a non god is God.
We and everything in the known and unknown universes or multiverses is a unified,simultaneous dynamic and ongoing dream of God. We are in His mind and we express His energies and potentials. We cannot be even in an instance to be outside of His realm. Nothing can separate us from God and from His love. It is love, the force and energy of love that keeps the atoms together in perfect chaotic vibrations in its electromicroscopic level.
As such, being a dream and in His dream, our real existence is in God, our mind is but a microscopic manifestation of God's consciousness. Our material existence is an integrated amalgamation of spiritual elements kept intact and matrixed with the same force of love. There is no life outside of God because there is no outside. All are IN because God is All and fills everything.
Religion in its essential duty is to bind man into this knowledge so that man's being guided by this teaching his heart inspired will find God that is not made in any man's likeness. We came from God. God does not come from us. Religion must teach eternal truth that spiritual truth can be obtained with reflections of material scientific factual repeatable truths amplified with light of the divine. Science and Religion is a pair of wings of the same bird. Without the other religion is lame. Fanatics are born of religion without science. Atheists are born of religion based solely in science.
God is energy, never created cannot be destroyed exist everywhere in the universe..that is His physical material existence and yet still all are His dream and in His dream, watching intently and active every instance of unfolding and mutation, creation and cessation.
