Not so, on multiple levels. Your last sentence there is just flat-out wrong since my philosophy is explicitly cosmicist, which means I regard the universe at large as being "much greater than us" (and therefore potentially horrific, as HP Lovecraft said). That feeds into atheistic pantheism, for me.

The talk of the creator's right is equivalent to talk of the creator's power, which means that that evaluation is amoral. God has power over his creation, but that's not the same as saying he's morally right to impose himself on his creation, especially if the creation is a person. Hence the debate about AI, for example: if we create artificially intelligent robots, do we have the right to enslave them? The answer isn't obvious, so just being a creator doesn't give you the moral right to dispense with your creation however you want.
