Well according to Rene Descartes, if I remember correctly, it works inevitably down to only a single being perfect enough for self-creation. We can't have a bunch of beings perfect enough to just go poppin' up all over the place uninvited (in this case, Talad and Laanx). But what I'm suggesting is sort of like the Theology of Tolkien's Silmarillion, where there is a supreme, self-creating god who created the other gods (in this case, that would be the omnipotent Universe herself), and then the other gods created the inhabitants of the earth.
