Lyric discussion by trypticsoyagar 

when i listen to this song i imagine the singer on one of those stargazing nights -- he thinks to himself about the universe and life

eventually he concludes for himself that "light and dark are on and off" (or the earth is light, filled with life, and dark is the universe, not with life). "and all that is left is us"

"what turn to green to brown" suggests death, and even kids know that "what makes the ground... greatest", obviously us humans. we are cursed with consciousness, but it also makes us the greatest over all other organisms.

"What they turn from green to brown" I interpret this as Nature being destroyed by humans (they).

Nature and music (What makes the sound/What shakes the ground) any child will tell you are the greatest things in life.
