It's obvious that you are trying to fit the concept into a world that is only physical.

What you describe is not possible in that paradigm of thought, the rule-set of this physical reality does not allow for what you describe.

Even so more when your understanding of what consciousness is, consciousness is not a random configuration of matter that constitutes a specific awareness. That specific awareness is not dependent on physical matter to exist.

What kind of mechanism is there to transfer non-awareness into awareness that is purely physical? You must explain that first.

I don't know why you are trying to explain a non-physical concept with something physical. It is more logical to explain it in non-physical terms and then evaluate the reason in it.

You will be able to evolve your theory if you don't confine yourself to physicality.
