Truly, Scripture makes various distinctions between the physical body and the spiritual body (where/when or autonomy of a being.)
To me, the physical body of Adam and his line becomes relevant first as a result of Adam and Eve's shame resulting in Gods covering them with coats made of skins:
Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them. Genesis 3:21
And almost all things are by the law purged with blood; and without shedding of blood is no remission. Hebrews 9:22
More specifically, nephesh is the ordinary soul which all living creatures have (Genesis 1) and is returned to the earth upon death, e.g. plants, bacteria, insects, animals.
And neshama is the breath of God which Adam received in Genesis 2 whereby he became a living soul.
Further, according to the mystics, the ruach is the soul pivot whereby the man chooses to be Godly-minded (neshama) or earthly-minded (nephesh.) That choosing parallels Romans 8.
And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. John 1:33
In that view, everything returns to the earth at death and new epiphenomenons begin at birth or conception.
But the Scripture speaks of creation being mindful:
Conversely then, the living souls which have ruach (choice) and/or neshama (breath of God) would "phase change" (if P.S. Wesson is right in the article linked below) and continue "in" the creation past the death of the physical body, i.e. autonomous where/when.
We review the idea, due to Einstein, Eddington, Hoyle and Ballard, that time is a subjective label, whose primary purpose is to order events, perhaps in a higher-dimensional universe. In this approach, all moments in time exist simultaneously, but they are ordered to create the illusion of an unfolding experience by some physical mechanism. This, in the language of relativity, may be connected to a hypersurface in a world that extends beyond spacetime. Death in such a scenario may be merely a phase change.
But despite all such speculation, we Christians being indwelt by ruach Elohim already exist "beyond" anything physical at all (including a phase change upon physical death):
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. - Romans 8:1-9
What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own? - I Corinthians 6:19
God's Name is I AM.
The book of Job, Chapter 38-42.
God flat-out tells us that we will never understand. How could we?
