Is Quran the proof of God?

[Brian37]

I can point out in all the books of Abraham, not just the Koran, where this god calls for or commits violence and murder on rival tribes. It is the same god character.

Cruelty justified in the Quran

Now, if either of these books were universal to humans, and god wanted us to not be violent, then the fact that it contains violent depictions makes it easy for insecure, or jealous or power hungry individuals or groups to cherry pick the books to justify their actions. The fact that non violent humans use them to justify compassion, does not change that it is the same book with the same words. And what would that say about the claimed attribute "all powerful" as a claim? If your goal is to have people get along, why go out of your way and have fallible humans write it for you then blame them for the confusion you didn't have to let happen? Hardly efficient if your goal is peace.
