ONTOLOGICAL ARFUMENT: “God is that which nothing greater can be imagined…” Argues that because as humans, we could not possibly comprehend God, you cannot imagine anything greater than God, therefore god exists. Even if you can imagine something that is not real that is greater than God, this imagined thing would be greater if it were real, and therefore must be God, considering there is nothing greater than him. The greatest thing exists in reality, therefore God exists.
