" And because, since the 1960’s forward, measurements of the cosmic microwave background radiation consistently agree that the universe is expanding – that there was a beginning of real space and real time – we know that there was creation ex nihilo."

No. There is no such thing as ex nihilo creation. The physics of this world arise out of a more fundamental physics as a phase change. That fundamental physics the physics of this world arises out of always existed.

" All physical cosmologies (inflationary theory, cyclic, imaginary time, multi-verse, ekpyrotic, etc.) require space and time for physical causality.

The geometric dimensions of this world apply to the physics of this world only, not to any other. If you are going to talk physics, keep in mind that the fact that this 4d world arose out of a more fundamental physics of higher dimension. It did not arise out of nothing as in the nonscientific claim of ex nihilo by virtue of the conservation of energy.

To the contrary, spunkets, all prior existence physical cosmologies rely on space and time for physical causation: multi-verse, brane theories, etc.

All they do is push the goal post further back to prior physical causation.

In the absence of space, things cannot exist.

In the absence of time, events cannot occur.

Physical causality requires both space and time.
