Answer:
What can be heard and caught but never seen?
The strangest creature you'll ever find has two eyes in front and a hundred behind.
I'm tall in the morning and short in the noon. I disappear at night but I will be back soon.
They made me a mouth, but didn't give me breath. Water gives me life, but the sun brings me death.
It cannot be seen, cannot be felt, Cannot be heard, cannot be smelt. It lies behind stars and under hills And empty holes it fills. It comes first and follows after, Ends life, kills laughter.
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
