I suppose an alternative is asking your students to ponder the question of what evidence there is for the Creator, and leave open the possibility of being Creator-agnostic. Clearly in a world like the WOT-verse, the prior for a supernatural creator deity is much higher, given that there's a pretty well established supernatural anticreator deity, so there's not much call to be an a-Creatorist, but even if we know from authorial say-so that the Creator exists, there's not necessarily anything wrong with acknowledging from a character perspective that there isn't enough data to be confident.
