Years ago, I started trying to fathom how it all began, the order of 'unfolding'. That's why I've settled upon the notion of continua I express as where/when continua. Even the soul and spirit exist in a continua of some expression of space and time.
The 'first' continuum was point/moment. During the inflationary phase, the universe went from point/moment to linear/moment, linear/past, then linear/present, planar/present, etc. and eventually volume/future. But the expressions 'present' and 'future' I do not think of the same way traditional 'one variable of time' notions assert.
I best stop before the ridicule rains down, as it has in the past when I sought to share this 'different' cosmology.
I gather we agree that the Big Bang theory calls for a singularity which is a mathematical point. And from there dimensions are created as it expands, e.g. space/time continuum. Or to put it another way, space/time does not pre-exist, it is created as the universe expands.
Observations of the Cosmic Microwave Background radiation shows that photons (physical light) came into existence about 300,000 years after the Big Bang based on our present space/time coordinates. Interestingly, the CMB records the sound waves at the moment physical light came into existence.
That, of course, always reminds of "Let there be light" or as you put mentioned earlier, "Light be."
But such measurements only apply to the observable universe.
For instance, by definition science cannot say that massless particles which have no direct or indirect effect do not exist, i.e. they cannot be observed. Or that fields which have no direct or indirect effect do not exist. Or that other types of dimensions which have no direct or indirect effect do not exist.
Physical cosmologists rarely speculate about non-observables.
Wesson's point that physical death is merely a phase shift ("in" 5D2T space/time) is particularly fascinating to me. I don't know if such a phase shift in 5D2T would be observable but in any case, that there may also be unobservable dimensions/fields bring various Scriptural events to the table, as you have noted.
The soul/spirit (whether associated with a physical body or not) is still a "thing" or "being" and experiences "events" which means it is "in" the continuum though it may not be measurable by a scientific observer in 4D. To put it another way, in the absence of space, things cannot exist. In the absence of time, events cannot occur.
I suspect some scientific observers prefer to associate everything mind related to a physical brain simply because they cannot physically measure the mind, soul or spirit. Thus they call the mind an epiphenomenon, a secondary phenomenon which cannot cause anything to happen.
