Here's one that took me ages to find out. See if you can get it faster than me:

Who makes it has no need for it.
You can catch it but can not throw it.
Give me food, and I will live; give me water, and I will die.
The man who invented it doesn't want it. The man who bought it doesn't need it. The man who needs it doesn't know it.
The poor have it, the rich need it and if you eat it you'll die.
I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place.

What am I?

This seems like a couple of riddles mixed together:
You can cath it but can not throw it.
Give me food, and I will live; give me water and I will die.
-Fire
Who makes it has no need for it.
The man who invented it doesn't want it. The man who bought it doesn't need it. The man who needs it doesn't know it.
-A coffin
The poor have it, the rich need it and if you eat it you'll die.
-Nothing
I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place.
-The letter e
