Comparing The Bible and the Quran. Which book is the greatest?

The Bible is a word which means, "collection of books."
This means all books, verses, chapters, were written by men.

In this holy book we have scenes of pornography, bloodshed, etc. We even have different versions contradicting each other.

There are king james version, queen james version, new international version, revised standard version, new living translation, good news, to mention but a few. All of which contradicts each other. Now, we don't have anything like different version of the Quran. Also, there is nothing like Indirect speeches in the quran. We only have all this in The Bible .

Again, the only Quran have been mathematically and scientifically proven to be the Strong Word Of God.

Can any man write such an organised and glorious book for just 23years?

Never!
The Quran even dared anyone to produce a book like it but still, no one has EVER SUCCEEDED IN PRODUCING A BOOK LIKE THE QURAN!

Unlike bible, in which we have tens of versions created and reproduced by human understanding and doctrine. To me, The Quran is the greatest book that was ever and can ever be in existence!
