Actually, I think you may have a point. The question of "what is life" is really not a scientific question. Yet, nevertheless, I am alive. In the same way, the question of "what is consciousness" is not a scientific question either. And yet, I am conscious. Consciousness exists. Science is just not applicable to these questions, because these questions have nothing to do with the core purposes of science: prediction. "Instrumentalism is the view that a scientific theory is a useful instrument in understanding the world. A concept or theory should be evaluated by how effectively it explains and predicts phenomena, as opposed to how accurately it describes objective reality." So science is about formulating frameworks for understanding observations in a way that allows for accurate prediction. To ascribe "metaphysical truth" to any of these frameworks is to take a leap of faith *beyond* science. Taking the view of "instrumentalism with a pinch of common sense", there is no reason to believe that every question that can be asked can be answered scientifically. Is there? Unless and until consciousness can be made useful for prediction, it will remain invisible and irrelevant to science.
