However, THE HARD PROBLEM of consciousness is that because we are within the system of physicality and can only interact with matter by our limited senses, there's absolutely no way to prove how this duality works, why it is so, or how we came to obtain self-awareness.

Then there's other theories and philosophies like Panpsychism that claims there is no duality. That matter of any expression has consciousness at varying levels.

So you and I are consciously observing our experience.. but so is the chair, and rock. etc.. even planets and the sun. Etc..
