Can a book like this be possible 14 centuries ago?

not written by man.. yes the Q'uran does reveal all this... many scientists have become muslim by the fact of discovering so much scientifically that was already in the Q'uran all them centuries ago. no person could have wortten these scientific facts in the Q'ran it has taken modersn scientists with the latest technology to discover all this so no man could have ever known this in 14 centuries ago God revealed it to the Phophet (may peace be upon him) so its not written by man but revealed by God!! logically wwhich man could posibly know all this back then to write such a book.. think about it for yourself...
