Just the opposite, by definition.

There is clearly SOME kind of deity-based moral code, else no one would have any hope of not only rebirth but SALVATION by which to swear. The Whitecloaks most definitely have an explicit (and extensive) moral code, but is hardly the case that everyone who is not a Whitecloak or Darkfriend is a default atheist: Everyone we encounter at least passively chooses to follow either the Creator or Dark One; there are no "theological Switzerlands." There is a default nominal and in some cases explicit religion (before we even get into the Dark Ones cult.) The very notion of a Dragon Reborn as Creators Champion, prophesied to return and confront the Dark One at Armageddon, is very much a religion.

Jordan established the Creator as voluntarily non-interventionist (except for creation itself, and possibly that one time at Tarwin's Gap) but ANY Creator necessarily has all the attributes and abilities of a deity, so debating whether or not it "actually" is one is semantics. If it looks, walks and quacks like a god, and can intervene in existence at any time, up to and including unmaking what it made, it is a god. Whether we choose to explicitly call it that, and whether it chooses to act on its ability to intervene, does not change that.

Honestly, the series' WHOLE PREMISE is eschatology drawing primarily on Judeo-Christian apocalyptic literature with a heavy sprinkling of other religions as well. Are we seriously debating whether a world inspired by religious apocalyptic literature has a deity or religion of its own?
