Child of Dust is written from the perspective of the element of Earth. The entire song tells of how Man was created as a child of Earth, yet as we grew, we "rebelled against our parent (the Earth)" by building, warring, and desecrating the planet. At first the Earth is confused as to why we destroyed it's beauty, but as we die, the Earth still takes back our bodies (as we bury our deceased), and protects them. The message behind this song is that no matter how we advance our civilization, we all came from the Earth, and one day we will all return to it.
