MUSLIMS why did allah have to reveal old known stories to mohammed in the quran..?

I can find a 50 year old empty book and write in it today or start to write on the backside of a sheep rug. Doesn't mean the book was written before I was born. Can they carbon date the ink?

Is carbon dating 100% accurate? Those questions need to be answered first.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
