Hey! Wanted to respond to you out of the thread.
"Just take scientific discoveries for example. Logically speaking, a man in the middle of the desert could not have possibly known about everything the Quran says, so I'd say it would be logical to believe that God does exist."
You're right to an extent, if we were to assume that Qur'an 1) was only written by one person, 2) was written from a person's imagination and 3) has not compounded over time.
But these are assumptions, aren't they? I mean, there's no reliable historical account for these to be known as "facts". If you take out these assumptions, we leave many possible interpretations of how Qur'an might have been written. One interpretation that I like, is that Qur'an is literally an improvement of the Bible, with elements of Greek wisdom (which was probably also popular in Arabia, but I'm not a historian so I can't say for sure).
