It's a meaningless question. How would a world without religion come about? By flipping a switch, and everybody becomes well educated, peace loving, hyper-rational atheists? In that case, probably yeah, it'd be better. On the other hand, if you start lopping the heads of anyone found to be taking guidance from any teaching that isn't solidly grounded in hard science, then, no, it certainly won't be better.

Do you forget what was responsible for spreading education so rapidly around the world (give you a hint, it wasn't atheists). There are a number of religions that are founded in rationality, and large components of others that are pure rationality. Just because you don't believe in (a) G/god doesn't mean you aren't r…
