What about the dust aspect of death? Dust you are, and to dust you shall return (Gen 3:19). If Adam returned to what he was before, and he didn’t exist before he was created, then how can we say he merely “separated” from his body. That means he (the part that is the essential him) did NOT return to what he was before, making God a liar.
If Adam was obviously highly configured dust, and upon death he would return to more randomly configured dust, rather than highly configured dust, which we are while breathing, that's also self-directed, highly configured dust; then it's disintegration of us that's death, there's the medical death where we stop breathing, and there's the complete disintegration that happens to our body, either accelerated by fire, or occurring slowly over the centuries, disintegrating completely back into randomly configured dust again.
How disintegrated are we? Did we just die, and so not that disintegrated, or have we been long dead, and we're further along the disintegration process?
The idea of our high configuration though, that idea always exists, even after our body disintegrates completely, the idea of its integration lives on, it's impossible for it to be destroyed. I'm just talking about the idea, or the thought, of our complete integration, when we're self-directed highly configured dust, breathing. That concept exists, not only after we die but before we live, logic doesn't grow with time, the available space is always the same, so just the idea of me, and of you, existed from the beginning of time, logically. It will exist until the end of time, whatever that means. It's certain.
The logical possibility of me and of you, existed from the beginning, whenever or whatever that was. Or, it existed forever, whichever you prefer, but the point is that it was never added to logical space, it was always there in logical space, just the idea, not that the idea would necessarily materialize, but it as an idea, existed.
The idea of Jeff Bezos flying into space existed from the beginning of time as well; I'm not trying to say anything profound, but rather, trivial.
All I'm trying to say is that this trivial observation about logic, that it basically eternally 'contains' all real possibilities, might be related to or how 'the essential us' persists after bodily death. And if God can create
ex Nihilo, then He can surely create another materialization of the eternally existing idea of me and of you, at some later date. And we might also have before then, some other form of materialization, or even two different other forms of the eternally unique idea of you and me, temporarily materialized in some way.
