The only reason any part of the world is backwards and underdeveloped is because of religion and shamanistic bullshit.
You'd be amazed how many smart and modern people know that God or the wonders of the bible didn't exist and still call themselves religious and somehow believe in it. I mean, we have theology on western universities, right? They study and know every detail about how each tiny fragment of bible text was written, rewritten and edited by hundreds of people, still they somehow believe in it as a godly thing.
It is a strange thing and perhaps only a relict but I think it was very crucial for the secular development of 'the west' that you could both be scientific
and religious.
Also historically your statement is questionable at least, christianizing europe was the only method that actually worked to get people united and 'civilized' in early middle-age. Now it seems we don't need christianity anymore, but how do we got other religions like Islam into that state of secularism and science? Is it the natural evolution of religions, are Muslim behind our timeline or is the Islam not capable of that kind of groundbreaking reform?
