is there any proof that show Koran not from human and is from God?
1- It was opposite of most scientific and nonscientific beliefs of people of 1400 years ago that leaded to wars between prophet and Arabs. So Koran was not copied. People had 360 God and stars were daughters of God and many more silly beliefs. I suggest study context of Arabia at that time.
2- Koran said earth is round
3- Koran said sun will turn off one day
4- Koran has many amazing numbers in words letters ,.. that makes many amazing facts.(more than accidental)
5- Koran says sun is moving
6- It is 1400 years Koran is shouting http://tanzil.net/#trans/en.sahih/17:88 and Koran has many enemies but no one claimed could. Many tried but it was not more than joke. (themselves accepted. Fact in history until now)
Koran said human can pass layers of skies and earth and can go to skies but needs some power. and even said human can control moon and sun and what are in skies:
7- Koran describes the steps of growth of fetus in womb in 7 presise.
8- Koran appeared in city of Mekka that many conservative Jews and Christians also lived there and they had high power. Also many enemies of prophet among Arab all were trying to disprove and destroy new prophet. Koran may times claimed you can not make a book or a chapter like Koran. Indeed if they could they made a book similar to Koran against Koran to not cost for war. But there is not still any book similar Koran.
9- Koran was said during 23 years by prophet. You know the ideas of a writer changes over time. But Koran has not even one internal contradiction or conflict.
10- There is many facts in history many famous people in Arab wanted to destroy Koran but no one could.
11- There is no proved conflict in Koran with science.
they are only some facts about Koran.
