There is no doubt a god, the question is what is it?

[Mystic]

If I can prove my creed with just Plato and Socrates, what would you say?

I'd say "that's a first"

You would say...it would not a be a first. In fact, much of Quran is allusions to their words almost as if predicted us uncovering the Greek philosophy treasures.  If you remember what Plato talks about and Socrates and the navigator in the just city, so much of the parables in Quran will make sense.

In fact, there exist some hadiths which some Muslims did believe in, that Socrates was originally a  Prophet. I can't vouch for that being a reality, but if you study Socrates and Plato, much of the Quran is emphasizing what they emphasized on with the flow and parables they emphasized on.
