Meditations Part 5 page 88

"But if, from the mere fact that I can bring forth from my thought the idea of something, it follows that all that I clearly and distinctly perceive to belong to that thing really does belong to it, then cannot this too be a basis for an argument proving the existence of God?"

So if we inherently understand everything and only having to remind ourselves about something we perceive to be foreign to us and that all of us are in fact born with an idea or image that does not exist in the real world, but at our discretion can in fact exist then Descartes has proved the existence of God. Right?
