To prove the Quran

There are 4 verses in the Quran that give a method of proving that the Quran is true. There are quoted below in Sahih International version:

And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah , if you should be truthful. (2:23)

Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah , if you should be truthful." (10:38)

Or do they say, "He invented it"? Say, "Then bring ten surahs like it that have been invented and call upon [for assistance] whomever you can besides Allah , if you should be truthful." (11:13)

Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants." (17:88)

Basically the Quran challenge us to bring a book or a chapter like it. To accept this challenge, we can conduct a test. Create Arabic verses like the Quran and mix the real Quran surahs in it. Get those who know Arabic to identify the real Koran surahs. If everyone who reads this mixture is able to correctly identify the real Quran surahs, then the Quran must be special. If not, we can prove that the Quran can be duplicated and the above quoted surahs are false.
