Does Quran prove God?

[Gwaithmir]

Your identity is interlinked with perception and requires it (whether brain generates or something else).
You have an exact valued identity.
Nothing can see you exactly as you are but God.
Therefore God exists.

There was Erú, the One, who in Arda is called Ilúvatar; and he made first the Ainur, the Holy Ones, that were the offspring of his thought, and they were with him before aught else was made. And he spoke to them, propounding to them themes of music; and they sang before him, and he was glad. But for a long while they sang only each alone, or but a few together, while the rest hearkened; for each comprehended only that part of the mind of Ilúvatar from which he came, and in the understanding of their brethren they grew but slowly. Yet ever as they listened they came to deeper understanding, and increased in unison and harmony. (The Silmarillion: Ainulindalë 1:1)

Nothing can see you exactly as you are but the One. Therefore, Erú Ilúvatar exists.
