I'm not misinformed on this matter, I'm being precise.
The perfection of the Quran is an important point since it justifies the existence of the faith vis-a-vis Christianity and Judaism, something Islam claims to correct (a pretty bold claim). It also reinforces the Quran being a miracle in itself.
If it's miraculous that the unaltered word of God came to us after over 1300 years, then there's something off if the divine information it contains is not so reliable. To you, of course, as a believer, it might be almost as miraculous, but to someone like me who doesn't believe, it just looks like another man-made faith.
Yes, I know, if you believe in monotheism, it's great to think like-minded people like you from other faiths all believe in the same god, it's like being one big family. But I see it like Zeus and Jupiter, obviously they are the same god, but they were part of different mythologies from different people and these gods didn't act quite the same so I view them as different entities. So by calling them as they are known, you know which one I'm refering to. No confusion.
The Quran is a completely mathematical book and this has only been found out recently by putting the book into a computer:

There is no way Mohammed recited all of this knowing the mathematical structure of it. The Quran itself even references the number in a verse:
[Quran 74:30] Over it is nineteen.
[Quran 74:31] We appointed angels to be guardians of Hell, and we assigned their number (19) (1) to disturb the disbelievers, (2) to convince the Christians and Jews (that this is a divine scripture), (3) to strengthen the faith of the faithful, (4) to remove all traces of doubt from the hearts of Christians, Jews, as well as the believers, and (5) to expose those who harbor doubt in their hearts, and the disbelievers; they will say, "What did God mean by this allegory?" God thus sends astray whomever He wills, and guides whomever He wills. None knows the soldiers of your Lord except He. This is a reminder for the people.
[Quran 74:32] Absolutely, (I swear) by the moon.
[Quran 74:33] And the night as it passes.
[Quran 74:34] And the morning as it shines.
[Quran 74:35] This is one of the great miracles.
[Quran 74:36] A warning to the human race.
[Quran 74:37] For those among you who wish to ADVANCE OR REGRESS.
[Quran 16:120] Abraham was indeed an exemplary vanguard in his submission to God, a monotheist who never worshiped idols.
[Quran 16:123] Then we inspired you (Muhammad) to follow the religion of Abraham,* the monotheist; he never was an idol worshiper.
[Quran 10:105] I was commanded: "Keep yourself devoted to the religion of monotheism; you shall not practice idol worship.
[Quran 3:95] Say, "God has proclaimed the truth: You shall follow Abraham's religion - monotheism. He never was an idolater."
[Quran 4:125] Who is better guided in his religion than one who submits totally to God, leads a righteous life, according to the creed of Abraham: monotheism? God has chosen Abraham as a beloved friend.
[Quran 2:135] They said, "You have to be Jewish or Christian, to be guided." Say, "We follow the religion of Abraham - monotheism - he never was an idol worshiper."
[Quran 6:75] We showed Abraham the marvels of the heavens and the earth, and blessed him with certainty:
[Quran 6:76] When the night fell, he saw a shining planet. "Maybe this is my Lord," he said. When it disappeared, he said, "I do not like (gods) that disappear."
[Quran 6:77] When he saw the moon rising, he said, "Maybe this is my Lord!" When it disappeared, he said, "Unless my Lord guides me, I will be with the strayers."
[Quran 6:78] When he saw the sun rising, he said, "This must be my Lord. This is the biggest." But when it set, he said, "O my people, I denounce your idolatry.
[Quran 6:79] "I have devoted myself absolutely to the One who initiated the heavens and the earth; I will never be an idol worshiper."
[Quran 6:80] His people argued with him. He said, "Do you argue with me about God, after He has guided me? I have no fear of the idols you set up. Nothing can happen to me, unless my Lord wills it. My Lord's knowledge encompasses all things. Would you not take heed?
[Quran 6:81] "Why should I fear your idols? It is you who should be afraid, since you worship instead of God idols that are utterly powerless to help you. Which side is more deserving of security, if you know?"
[Quran 6:82] Those who believe, and do not pollute their belief with idol worship, have deserved the perfect security, and they are truly guided.
[Quran 6:83] Such was our argument, with which we supported Abraham against his people. We exalt whomever we will to higher ranks. Your Lord is Most Wise, Omniscient.
[Quran 60:4] A good example has been set for you by Abraham and those with him. They said to their people, "We disown you and the idols that you worship besides God. We denounce you, and you will see nothing from us except animosity and hatred until you believe in God ALONE." However, a mistake was commited by Abraham when he said to his father, "I will pray for your forgiveness, but I possess no power to protect you from God." "Our Lord, we trust in You, and submit to You; to You is the final destiny.
[Quran 60:6] A good example has been set by them for those who seek God and the Last Day. As for those who turn away, God is in no need (of them), Most Praiseworthy.
I will make another point with these verses:
[Quran 6:115] The word of your Lord is complete, in truth and justice. Nothing shall abrogate His words. He is the Hearer, the Omniscient.
[Quran 10:37] This Quran could not possibly be authored by other than God. It confirms all previous messages, and provides a fully detailed scripture. It is infallible, for it comes from the Lord of the universe.
[Quran 41:3] A scripture whose verses provide the complete details, in an Arabic Quran, for people who know.
[Quran 18:1] Praise God, who revealed to His servant this scripture, and made it flawless.
[Quran 18:2] A perfect (scripture) to warn of severe retribution from Him, and to deliver good news to the believers who lead a righteous life, that they have earned a generous recompense.
[Quran 4:82] Why do they not study the Quran carefully? If it were from other than God, they would have found in it numerous contradictions.
[Quran 54:17, 22, 32, 40 ] We made the Quran easy to learn. Does any of you wish to learn?
(These verses are referring to people such as yourself who choose to be skeptical of it):
[Quran 17:41] We have cited in this Quran (all kinds of examples), that they may take heed. But it only augments their aversion.
[Quran 17:46] We place shields around their minds, to prevent them from understanding it, and deafness in their ears. And when you preach your Lord, using the Quran alone,* they run away in aversion.
[Quran 12:103] Most people, no matter what you do, will not believe.
[Quran 12:106] The majority of those who believe in God do not do so without committing idol worship.
