even after seeing all the signs u all deny them,

what is the reason that quran ,which was revealed 1400 years ago, consists the scientific facts which are proved very recently?

and for those who say that prophet muhammed(pbuh) might have copied , made some vague ideas etc..

please study the history of islam.. and the quran

prophet muhammed(pbuh) was unlettered, ie he didnt know how to read or write,

secondly , revelations started coming to him only at the age of 40. and before he was famous among every one as truthful and honest
