Part IV (The Index Fossil) lyrics

we're widespread and well fed
the earth's rotating fate is in our head,
we're dominant and prominent and all our
deities omnipotent,
and immortality is in our mastermind
and we destroy everything we can find,
and tomorrow when the human clock stops
and the world stops ticking,
we'll be an index fossil buried in our own debris
we're listless, promiscuous,
and life to us is either hit or miss,
we're savior faire and debonair,
and things we do are done with pride and care
