Where is in the brain. Science doesn't usually answer "why" questions except in the general sense of evolutionary adaptation. How? we don't know exactly. But having an unanswered question doesn't constitute a deep mystery that demands new physics.

Do you ever read what you write? That sounds like something Geore W. Bush believes.

Sure we do. We accept it as evidence of our evolutionary adaptation to survival on Earth.

That's your assertion - but repeating it over an over doesn't add anything to its support.
Maybe some new physics is implied by consciousness (as in Penrose's suggestion) or a complete revolution (as in Burno's UD), but it is far from proven. I don't see even a suggestion from you - just repeated complaints that we're not recognizing the need for some new element and claims that you've proven we need one.
