The One Who riddle

The one who makes it sells it;

The one who buys it doesn’t use it;

The one who’s using it doesn’t know he’s using it;

What is it?

What am I?

When you have me,

you feel like sharing me.

But, if you do share me,

you don’t have me.

What am I?

Great and Evil

What is greater than God,

More evil than the devil,

The poor have it,

The rich don’t need it,

And if you eat it, you’ll die?

What Am I?

Feed me and I Live

Give me Drink and I Die

What Am I?
