I think you will have the same problem that many theists have. You (must) assume that a good investigation starting from that "zero-point" would have to lead to the conclusion that (in this case) the Quran is truely the word of God.
Now the problem is that rather obviously for most "i start from zero" this definetly is not the conclusion that is drawn and those people are not all plain stupid or have a "wrong understanding".
As to your questions in above paragraph:
Why shouldnt a person in the 7th century write such a book? There is nothing in it in my view which couldnt have been written by humans. Actually there are many errors depending on the method you utilize to examine the quran.
As for your second question:
Just look at the number of different religions with all their followers which make the same claim that you do and you will see that there are more than enough other books that are in the same "quality level" as the quran.
Now you make a lot of claims about that scientific stuff.
I have had such debates already more than 20 years ago.
And i know that each generation there again come people that think this science claim to be true. Well IF you actually went over the quran in the way you asked others todo it and took into account science then you wouldnt even think about a second about this claim. There are no "scientific facts that were not known" in the quran unless you put them there using supposed knowledge of today.
Actually most of what is said in the quran which you PICK for science is (when analyzed with the same scrutiny as scientific claims made somewhere else) errorneaous.
Most examples that you mention actually are starting with the shape of the earth, the functions of the mounts and who knows what else.
Embryology is my favorite. A paid for special third edition of Moores book which never made it to any new edition and which never appeared ANYWHERE appart of arabic countries and "universities".
If you believe the quran to be Gods word then by mere declaration of faith you cant allow any contradiction to exist no matter how obvious it is. The verse like this challenge has already been met before my lifetime and duringmy lifetime again and again. I myself have already met it with more than enough muslims. It only depended on whether they thought it was from the quran or not.
Actually the challenge itself is already a display of imperfectness for no challenge makes sense if no clear rules for the challenge are given. And we can see in this forum how the challenge is interpreted depending on the answers that are given to meet it.
Instead of asking others to investigate the quran neutrally (which was/is done by many) you should do so yourself first
