Full Idea

A thing necessarily exists if no cause or reason be granted which prevents its existence. No cause can be given which prevents the existence of God, or which destroys his existence, so we must conclude that he necessarily exists.

Gist of Idea

God must necessarily exist, because no reason can be given for his non-existence

A Reaction

I can't think of any reason why there shouldn't be a giant rat which fills a large proportion of the universe. Indeed, it may be the missing 'dark matter'. So presumably it has necessary existence. Proving non-existence is obviously tricky.
