Yes. Pre-modern times. Not modern times. Meaning you tacitly admit that in modern times we don't need it to create order. For that we have laws, which are guided by founding principles and more importantly an understanding of why those principles are the way they are. I flatly reject the claim that religion "helped created peace", when the entire history of warfare is full of justifications on behalf of religion as early as we know. People are equally persuaded to warfare by those same promises of heaven or punishment.

In other words, your justification here, your reply here, is a contradiction with your original thesis. You claim in the original that it's somehow still necessary, but you defend it by proclaiming some supposed ideal in the past you allege exists without evidence. It has never truly been religion that creates civility, from the very earliest it has been legal codes and governance (see also: the code of Hammurabi). As modern times demonstrate quite well, most people can be without religion and observe the same things just fine.

Edit: As for the final nail in the coffin, now is the best of all times by any metric we have for the most of all people. Fewest crimes, fewest diseases, easiest lives, longest lifespan if you manage to not be an obeast. No actual metric supports your worldview, I assert, and I guarantee any you come up with I'm already familiar with and can state with absolute certainty is a lie (either of omission or otherwise). In fact, within nations and between nations, the correlation is CONSISTENTLY in favor of less religion being better.
