I think I disagree. The hard part is understanding why we have a sense of "self" one that can independently perceive it's place among the solar system and beyond.

The "colors, sounds, tastes, feels, etc" that you refer to can be seen as sensors that perceive narrow views of the various spectrums created by the energy bouncing around in the physical universe.

Examples:

- Hot vs. cold for a human is entirely different that hot vs. cold for a star.

- Color, from our perspective, is the spectrum of light that we need to utilize to effectively interact with our environment (different animals need and perceive different spectrums of light).

- Sound is a vibration that propagates as a [..] mechanical wave of pressure and displacement, through a transmission medium such as air or water. (taken from wikipedia.org/wiki/Sound)
