What would the world be like without religion?

Think about it, peace and prosperity. You wouldn't be able to say " OMG" anymore. You would have to say OMS. (Oh my science!) Crusades wouldn't have happened. Our whole race would have much better technology I believe because discoveries made long ago were put down because of the church. The theory of evolution makes perfect sense. Heck we even act like monkeys, uncivilized and filthy. Not to mention stupid. What I am trying to get to is that if the whole world were as one, striving for a goal, we would probably be colonizing different planets by now. I wish ether religion was gone totally or we had only 1 religion in the entire world.
