Your analogy of mouse killing was poor. First of all SU merely proposes a mouse killer. Somehow your analogy manages to conjure up a cat and mousetrap. SU does not afford that luxury because cats and mouse traps are subject to science. We know for sure we have an option there.
I wasn't referring to that analogy in the post you are ostensibly replying to, but to run with it anyway; even if you insist the SU only suggests a mouse killer (universe creator), then you are insisting that it's a cat (god).
In fact it's worse than that because SU proposes a naturalistic, technological civilization and theism proposes a supernatural being.
Secondly theism has got their first and labelled the intelligent creator. That you seem to think the idea of an intelligent creator isn't a central theme in religion shows how shockingly ignorant you are of theology. I think you've been influenced there by New Atheism.
Firstly, what part of "I've never said that (some) gods aren't intelligent creators of universes" are you finding difficult? I've also never denied that an intelligent creator is a central theme in many religions.
Secondly, this isn't a kindergarten game - you can't bagsy a concept just because you arrived at it first. As I said before, medical cures for previously incurable diseases don't have to be described as supernatural because religions had stories of them being miraculously cured first.
Thirdly, you still haven't provided a single reference that says that all universe creators are gods rather than gods being universe creator.
Fourthly, you haven't addressed the point that gods and universe creators cannot mean the same thing because some gods aren't universe creators.
You make a fair point by asking what constitutes a universe. Here we can go with Tyson who hazards basically that there is a high probability that this universe is simulated.
The "high probability" is based on a set of assumptions and is anyway irrelevant to my question.
So we could go with this universe as the model. Where the simulator seems to be separate and independent from it.
This is distinguished from simulations which are built inside and share materiality and physicality of a universe and are therefore part of the same universe as the simulator.
Sorry but I can't make any sense of that. A simulation would have to run on something (a computer or something equivalent) and that something would have to be in the same universe as the simulator. The 'physicality' of the simulation would be, err... simulated.
My point was that humans already run (limited, partial
*) simulations of this universe and explore 'universes' based on simple rules - like the
Game of Life that can actually contain self-replicators and Turing machines - despite it's simple rule set ('physicality' or 'basic physics', if you like).
PS:
Please take your time a read the above think about the points before replying.
* And if we are in a simulation, we can't be sure that it is a complete simulation of the/our universe.
