There is no religion in WOT. There is a general sense from the individuals in the WOT world that there is a sentient (although there is no proof of actual sentience) being who created them. There is also an "evil" force that clearly has sentience. None of is means there is an actual deity. The Dark One might wish to become a deity, but more likely seems to be a nihilist.

I see nothing in that which inherently means the "Creator" or the "Dark One" truly had anything to do with creation ... One of the main points RJ hit on throuhghout the series dealt with myth becoming legend in a never ending loop. What 3rd age WOT people discuss as the Creator could very well be some form of deity, but could just as easily be completely non-sentient, or an early myth with roots in the very real OP before man could comprehend what that force was. The DO could as easily be a human who discovered some alternate power source ... We are given zero explaination of how the DO truly came into existence. But the closest parallel seems to be from the Zoroastrian myths of Ahrura Mazda and Ahriman, which most of humanity today believes to be nothing more than ancient man putting context into creation. No reason to believe RJs construct of the Creator and the Dark One is anything more than elaborate myth. We know the 2nd Agers didn't believe in any sort of deity until the Dark One was freed and showed sentience. But that doesn't prove that the Creator is either sentient or a Deity.
