Answer:
I am enjoyed by some despised by others. Some take me for granted some treasure me like a gift. I last forever unless you break me first.
What force and strength cannot get through I with my unique teeth can do.
Sometimes dark and sometimes bright I make my way among twinkling lights. Seas and oceans obey my call yet mountains I cannot move at all. My face is marred and gray But I'm majestic anyway
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. What am I?
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. Sooner or later everybody needs my help yet many people are afraid to let me help them.
The answer I give is yes, but what I mean is no. What was the question?
