Is Quran the proof of God?

[GrandizerII]

Allah is not all-powerful, despite what Quran 30:54 and other Iyah say. For example, can Allah have a son? Yes or no?

Or can Allah forgive Shirk? Yes or no? Never understood why Shirk is worse than slavery or killing another human.

Have I not found things Allah cannot do? And that's putting aside the fact that I can't objectively test for Allah. What's a repeatable experiment to prove the existence of Allah?

Allah CAN do anything He desires for He is Almighty God.

Can Allah create a more powerful being than itself if he desired to do so? If not, then you're wrong.
