Re: all of the above. You do realise that my video was NOT claiming that there definitely are grammatical errors? I have been asked this question many times - ever since I used to post on FFI and I always insist that one simply cannot prove such a thing. My point is that one cannot prove the contrary either! The claim by Muslims that the Qur'an is perfect and that this proves it comes from God is not a claim that can be tested objectively. It is not a matter of ascertaining the facts and proving them beyond reasonable doubt. It is a matter of faith and not indisputable evidence.
Was that not clear in my video?
No. But I agree that no one can prove the divinity of the Quran, and that goes for the language as well.
