Answer:
Bury deep, Pile on stones, My mind will always Dig up them bones
Many hear me, but no one sees me, and I only speak when spoken to
Often held but never touched. Always wet but never rusts. Often bits but seldom bit. To use it well you must have wit.
I never was, am always to be. No one ever saw me, nor ever will. And yet I am the confidence of all, To live and breath on this terrestrial ball.
It comes only before, it comes only after. Rises only in darkness, but rises only in light. It is always the same, but is yet always different.
What never gets any wetter no matter how hard it rains?
