The Demiurge and the Problem With Evil in the World

I- It feels interesting to me that anytime you talk about a God or a creator, people really attach to sort of like a pure Christian. And I get why that happens particularly in our culture. But it's actually like, if you think that somebody created this world, there's no reason to believe that that thing also created everything. So why would you assume that there can't be others? Having like a single God feels like a very specific case of what God or gods could look like. That gives a misleading impression of what I'm talking about when I talk about encountering God.
