Descartes demonstration of Gods existence

I can’t understand why this proves Gods existence or the logic behind it, but Descartes seems pretty certain. 

his argument is essentially:
1. God is infinite, omnipotent, omniscient, and absolutely truthful 
2. everything has a cause
3. Therefore this idea has a cause
4. the cause of an idea has as much reality formally as is contained objectively in the idea
5. no being other than God has as much reality formally as is objectively contained in my idea of God. 
6. Therefore, God is the cause of my idea of Him. He exists. 


Can anyone explain how he got to 6? I don’t understand this string of logic.

There are two proofs in his meditations. 

Descarte's Ontological Argument states that a perfect being would necessarily exist for it to be perfect, for if existence was beyond its grasp it could not truly be perfect. 

Descarte's Cosmological Argument states that, since the effect cannot have anything that was not already in its cause ( since nothing comes from nothingness), God must be the only feasible cause for the idea of God in Descarte's mind.
