Let me further specify my request: provide a documented example of any religion (existing or disappeared) that introduced a new moral value which was not present (and documented) in the society where said religion appeared (absorbed moral value), or in societies with which said society was in contact (imported moral value). No need to go back to prehistoric periods. This is completely orthogonal to the belief question: that is, you could perfectly believe that Jesus is the son of God, and still you will observe that all moral values introduced by Christianity were already present in the existing society. Note: actually, to be precise, discussion with believers will always reach a point where rational discussion completely breaks down, since, by definition, humans can not understand the ways of God. At some point I will struggle to understand a situation which says the "wall is black and the wall is white", and a believer will rightly point to me that understanding this is simply over my head, and that I just need to accept it as it is.
