Oh, please, cut this cosplay out. In every surgery room of the whole world you could see how chemical compounds administered to patients would turn them unconscious and back. This implies that the consciousness is a product of the brain, not some immaterial substance, divine presence or other kind of abstract crap. This also implies that it is not mere an abstract idea of so-called pure reason ("soul", "I" and "god" are such idea, "awareness" isn't), but a valid linguistic label associated to a real high-level biological phenomena (a set of coordinated processes).

In every neurology department which deals with brain injures and pathology one could see the evidences that the states of consciousness and even its pretense or absence are bound by particular parts of the brain, which, in turn, is an artifact conditioned by the evolutionary forces and constraints of this particular universe and its physical laws.

The way medical science went from Phineas Gage to modern maps of the brain centers, insights into how the vision sub-system works, etc. constitutes the experimental proofs you are asked for.

The proof could be considered still incomplete (but nevertheless it is valid because there is not a single contradiction in what is experimentally confirmed), because there is no way to describe step-by-step the whole development from a single fertilized egg to you, but there is no doubt that there is nothing extra to that mere "mechanical" process, and that the mind is what the brain does and that conscious, which some people would call primordial awareness, is mere a product of the brain activity, which can be affected by chemical compounds and even switched on and off, which, BTW, happens every time you fall asleep (because it is not required) and wake up.
