No it's not. It's a formalization of St. Anselm's ontological argument. It's clear to me that you have no real interest in the subject, but on the off chance I'm wrong you can easily find both the medieval ontological argument and the modern formal one online.

In any event I think Gödel's proof is worth understanding simply as a nice example of modal logic and the power of formalisms. Anselm's informal attempt at a proof is famously unreadable.
