hi there! you are not the first person who is thinking in this way, Allah has challenged all those who don't believe in Quran, "And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah(meaning Chapter) the like thereof and call upon your witnesses other than Allah , if you should be truthful" Quran 2:23
1400 years passed, no once ever came up with a single chapter like the book, how strange!
for you information, smallest chapter number is 108, go and check how long it is.
Now i want to ask you, why no human being is able to accept this challenge of Allah?
