Consciousness sees the functioning of the brain argument

The hard problem of consciousness is often thought of as how does the functioning of the brain produce consciousness when actually the functioning of the brain is the consciousness that we experience. When we look out through our eyes we see reality subjectively. How is it that the brain produces this picture of reality? We do not actually see reality, we see the functioning of our brains. The brains structure has been shaped through our genes and interactions with the external world as we develop over time, to be able to produce ways of responding to the world that helps us survive. The science of superimmortality predicts that any brain that is structured and then functions identically to another brain will produce identical consciousnesses. It may be possible that there is only one way to produce a specific brain's structure and functioning but since there seems to be many different external ways to effect how the brain functions it would seem that there would be many different sets of external conditions that will produce identical structure and functioning in the brain. Do all of these different ways have to be connected to reality? Lets imagine the experiment where scientists manage to create a specific structure and functioning of a brain without a body with sense organs that is identical to a brain in a body that does have sense organs and a sense that they are connected to reality.
