Hey,i'm an atheist from India. While having a discussion with my muslim friend on religion,he told me that the qurran talks about the big bang theory and things about embryology and that the qurran even talks about the geo-spherical shape of the earth, these were only recently discovered by scientists only a few years back.Hence he says the qurran could have only been written by the creator of this earth since the qurran was written about 14000 years ago. How much of it is true,and how can i counter his claims?
