Couldn't we take the "ontological proof" of God's existence to prove that there are many God-like creatures? For instance, imagine a creature that has all thinkable perfections except for the fact that it has dirty fingernails. If existence is a perfection, then this creature must have this perfection, since one can both exist and have dirty fingernails. And so, if the ontological proof proves that God exists, then it proves that dirty fingernails-God exists too. Doesn't it?
