Agnostic atheism: a reasonable position on spiritual matters, or the only reasonable position...

13. Let's use the word cosmos instead of universe

As we are at odds over the term.

You are proposing there is something other than the cosmos in which we exist. Fine, there is nothing wrong with that, theoretical cosmologists do that all the time. The difference is that the theoreticians propose that there are some measurable effects within our cosmos - be it amendments or structures within the CMB, white holes, black hole decay or the decay time of the proton. What you propose is that there is something beyond the cosmos that has no measurable effect on the cosmos, nothing; there are no fingerprints in the CMB, no stars that explode or decay on an unexplainable schedule, no new arms being grown, no talking snakes or donkeys and the list goes on.

Given that we exist in a cosmos I can accept that there might be others. Equally I can accept the idea of a foundational dimension from which all else springs. But the point is that you have to define a term for the all, you cannot just abrogate responsibility and say "God is outside the universe/foundational dimension". To just declare He doesn't exist in space or time and cannot ever be detected is magical thinking of the first order.
