I find it amusing that some, who profess themselves to be wise attempt to explain the origins of the universe through the idea of "extra dimensional" origins. Yet.........they never consider the word of God that professes that God lives and abides in a Spiritual Dimension known as Heaven..........a Super (superior) Natural (to nature) realm.
God professes to be a Spirit.........."God is a Spirit.....to worship God we must worship in Spirit/mind" -- John 4:24. Men are created with a physical body..........yet, God declares men are made in His image. (Genesis 1:26). Reality: men are also created with a Spirit, "God breathed His Spirit, His breath of life into man......." -- Genesis 2:7 Therefore the image that man reflects of God..........is found within man's spirit. The Kingdom of God resides within the heart of man -- Luke 17:21 Whether we believe in God or not.........our spirit belongs to God and will return to God for final judgment after physical death (Eccl. 12:7)
Thus, I find it moot to argue about God's existence...........we shall all know in the end. And what has one lost if he attempts to live a life dedicated to the knowledge that God has revealed about Himself and His creation...........if nothing else we will leave this physical realm a better place than the realm in which we were born. On the other hand.........what does one gain though living a selfish life dedicated to self under the pretense that man created God instead of God creating man.......one does not gain one second of extra life in this vapor/mist we call life, but one does risk eternal damnation of his spirit..........that invisible force that animates the human animal. Where does this spirit/energy go at death? Its proven that energy, once in existence, cannot be destroyed only transformed. The Law of conservation of Energy.
