One of the most fascinating arguments for the existence of an all-perfect God is the ontological argument. While there are several different versions of the argument, all purport to show that it is self-contradictory to deny that there exists a greatest possible being. Thus, on this general line of argument, it is a necessary truth that such a being exists; and this being is the God of traditional Western theism.
Alvin Plantinga’s Modal Ontological’s Argument is a irrefutable logical argument for the existence of God. Yet many people seem to have a hard time understanding it. This video tries to simply the argument so the average person can understand it using William Lane Craig’s work.

Faithful Guide To Philosophy 9: Ontological Argument – Peter S. Williams
The Ontological Argument is one of the four great arguments for the existence of God, along with the Cosmological Argument, the Teleological Argument, and the Moral Argument. First invented by Anselm, this argument has gone through many versions. This current version is based on Alvin Plantinga’s Modal Ontological Argument, which does not assume that existence is a predicate, and so avoids Kant’s objection.
