Answer:
I am always hungry, I must always be fed. The finger I lick will soon turn red.
Name for zenith
It's been around for millions of years, but is never more than a month old. What is it?
Thousands lay up gold within this house. But no man made it. Spears past counting guard this house, but no man wards it.
It floats over the land, It cuts the tallest mountain, Its voice is like a fountain, Its body like a snake, Will flow into a lake.
You use it between your head and your toes, the more it works the thinner it grows.
