In the [Realm] you are discussing, this very well could be both a plausible and viable viewpoint of what is factually happening. But the original sin began with Satan, well before Genesis 1:1 took place (took place as when it happened/not when it was written). Sin happened in the Realm of Heaven long before God spoke the Universe into existence. And since we know Creation was how we read it in the Torah, we know evolution is false.
1. Sin originated in another Realm other than our own Universe.
2. God speaking Life into existence does not equal a Big Bang.
3. God's own Version of His Creation erases the idea of evolution.
These three reasons alone dispute your suggestion.
But the main reason your theory is far left, where [Sin] factually originated from. The sin particle is Satan, not portions of annihilated energy connecting the entire Universe.
Sin originated in a completely separate and different [Realm] than what connects to us directly, the Universe and our Planet we exist in.
So decoherence and retrocasuality do have a proper place in all things, but it does not exist in the Realm of Sin.
After all, Decoherence and Retrocasuality Exist in our Realm where we all originated from.
Sin originated from another completely separated Realm.
Therefore, this conversation is illogical at best!
