Modal Ontological Argument

The Modal Ontological Argument is a philosophical reasoning that suggests God's existence is logically necessary. It begins by defining God as a being than which nothing greater can be conceived. If we can imagine this being existing in our mind, then it's possible that it exists in some possible world. Since a necessarily existing being would exist in all possible worlds, including our own, this reasoning concludes that God exists necessarily in reality. Essentially, it uses concepts of possibility and necessity to argue that a perfect being's existence is logically required.
