on #3, no. There is evidence of what Aristotle and Socrates said and what they said can be proven in other sources. There is no other verifiable proof of the bible/quran outside of the bible/quran. In fact, there is nothing written in the bible/quran that could not have been written by first century CE man. If there is anything written in the bible that was not known or understood by first CE man then there would be an example of divine inspiration.
