This also reminds me of the transporter beam conundrum. Thing is, if you slice someone up at the molecular level, you have, by definition, killed them. What you get at the other end is another “copy” of the person. But here is the important part: They would be dead as well, since nobody “breathed life” into them. Not a single cell would be alive. Not a single muscle would be alive, though it would be “fresh meat” as you see in the grocery store.
It would be organic, but it would not be alive. Not one single cell would be alive. Every cell would be dead.
I reject your premise. Why at the molecular level?
Why not at the (obvious) atomic level? Better yet, at the fundamental particles level?
Together, of course, with a controlling "database" mapping the reassembly. Think big.
But let's bypass the BS.
If there is an omnipotent God, by definition, anything is possible. Isn't that the essence of the word "omnipotent?"
