Greater than God?

From:  "Ray Johnson"

What is greater than God, More evil than the devil, The poor have it, The rich need it, And if you eat it, you'll die?

Your very own new webmistress came up with this answer:

Its nothing. Nothing is greater than god, nothing is more evil than the devil. The poor have nothing, the rich need nothing. And if you eat nothing, your definitely going to die.
