Ontological Argument for the Existance of God

1. God is that than which nothing greater can be conceived.
2. It is greater to be necessary than not.
3. God must be necessary.
4. God exists

Logically speaking, God MUST exist. But what God actually IS, no one really knows. He can be energy, mass, or some sort of spiritual being. All of these three fulfill the description: cannot be created nor destroyed.

No. It is based on the assumption that there is a "greatest thing in existance", which by the well-ordering axiom (there are a countable number of atoms in the universe, thus a countable number of objects in the universe, thus a greatest object in the universe). Thus, I've demonstrated there is a "greatest object in the universe." Step 1 merely was defining this thing to be God. Now, it may be a Looney Tunes cartoon, or a cup, or a table, or an oxygen atom. The important thing is that I've just proven with maths that there exists a "greatest thing" or at the very weakest, a set of "greatest things". Then we give name to this thing, or the set of things: "God".

Not a proof that God is the Christian God, just that whatever Step 1 defines "God" to be actually exists.
