The whole social history, progressive society thing is only the Christian perspective.
For example, in Thailand ladyboys I.e. transexuals, are revered as being the closet to the gods in that culture. They have a positive, mythical status. The complete opposite to the (historical) Christian attitude towards transexuals being deviant.
My point being, if you wish to suggest Christianity has helped the world organise and civilise itself you are looking at the world through a very narrow, and probably biased because of your personal faith, perspective.
