Why is anything conscious? Both biological and other physical systems process information, yet humans consciously experience as well as process information. Why?
Unlike physical systems, biological systems are dissipative systems using energy to self-organise in the face of entropic decay and environmental perturbation.
Self-organisation is typically defined as the spontaneous emergence of spatiotemporal order or pattern-formation processes in physical and biological systems resulting from interactions of its components with the environment.
Instead of considering the body as a mere device designed to fuel and contain the mind (a device that can be replaced with a vat or a robot, for example), one must consider the mind as serving the self-sustaining needs of a surviving body.
All living systems experience the world through their bodies, and as such, there is something what it is like to experience the world in that basic way.
