@smj, that's missing the point a little. The debate was about what people believed
at the time the bible was written.
Science fiction and fantasy writing are all modern phenomena. For example, in the New Testament it mentions that on the Day of Judgement, the dead will
literally rise from their graves on Earth to face judgement. All supernatural phenomena were in fact viewed as being very closely aligned with observable physical reality. These religions were not being advocated to literate people with advanced concepts such as non-physical planes of reality and the like, they were being advocated to peasants who only knew basic physicality.
Religions only really got into the "yes but it's to ethereal too be seen ~woooooo~" stuff after the rise of science started challenging religious doctrines. When religion dominated explanations of the real world they merely stated outright that the universe adhered to their own set of rules and there was no reason to speculate about hidden realms. God was up in the sky, and that's all you needed to know. End of debate. It's only doctrines on the decline that need to start dealing in "yes but you can't see it" stuff.
https://en.wikipedia.org/wiki/Celestial_spheresEDIT: For example, read through the Celestial Spheres stuff and you can see that they believed that outside the opaque sphere which holds the stars up, there's the realm of Gods/Angels/Ascended people. And the claim was made that it would take 8000 years to
walk to the star-sphere. i.e. a completely physical place "up there" but just too far away for any human to get there.
