here:
1. God is the entity than which no greater entity can be conceived.
2. The concept of God exists in human understanding.
3. God does not exist in reality (assumed in order to refute).
4. The concept of God existing in reality exists in human understanding.
5. If an entity exists in reality and in human understanding, this entity is greater than it would have been if it existed only in human understanding (a statement of existence as a perfection).
6. from 1, 2, 3, 4, and 5 An entity can be conceived which is greater than God, the entity than which no greater entity can be conceived (logical self-contradiction).
7. Assumption 3 is wrong, therefore God exists in reality (assuming 1, 2, 4, and 5 are accepted as true).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. Therefore, it is necessarily true that an omniscient, omnipotent and perfectly good being exists. (By 3 and S5)
5. Therefore, an omniscient, omnipotent and perfectly good being exists. (By 4 and since necessarily true propositions are true.)
