Let's ignore entirely the particulars of what country professes which religion because it's totally irrelevant to the issue of development.

The Greeks believed in many Gods and briefly ruled a large part of the world and their culture has continued for over two thousand years to be the a fertile seed source for many other nations and empires to draw on effectively.

The Romans borrowed much of their religion from Greece but added Emperor worship to the mix, then mixed it up with early Christianity and they ruled a vast empire for centuries.

Medieval Europe described itself as Christian, one God who is somehow 3, it was always at war within and rapacious in it's attentions elsewhere, while simultaneously producing astonishing intellectual and cultural and eventually industrial/economic fruits starting with Greek ideas and then going in all kinds of amazing directions.

The Americas hosted many mighty empires, many of which endured far longer than the recent cultural dominations of christian Europe and Nth America. Generally their Gods were bloodthirsty and warlike.

China has an astonishing history of stability and empire (Vastly pre-dating Europe, the Greeks, the Americas.) in which Confucian thinking, primarily ethical in focus, has been the dominant "religious" element, overlaying all kinds of tribal animisms.

The Middle East flourished culturally in the early centuries of Islamic hegemony.

That's just what I know off the top of my head. My point being that empire, economic growth, cultural fecundity, social stability, are qualities that have been demonstrated in societies based on many different religious platforms.

For a more reasoned and fascinating explanation of the fates of human societies, take a good look at Jared Diamond's Pulitzer Prize winning book "Guns, Germs and Steel." Awesome book, so many fundamental insights in it you'll be chewing it over for a good year or two.
