Before you even attempt to answer don't forget to consider that time and space are in a state of perpetual motion
That depends on how you look at it. If we consider the spacetime universe as a single entity — which it is — it looks different... Motion is a function of time, nothing more.

I thought about your assertion for awhile..........And then decided to dispute it.
Ah, OK.

1. How do you know that "the spacetime universe as a single entity"
- Can you prove this
I think you might've read "as" as "is"? Read again: "
If we consider the spacetime universe as a single entity..."
Also, I don't think there's any need to "prove" something that can be confirmed by simple empirical observation, is there? It's there. It has no dividing 'lines' that separate some parts of it from other parts. Empirically, I can see no reason or justification for our assumption that the universe may be divided into distinct and separable parts.
That is dubious, wouldn't you say? But I offer no "proof". I'm not sure there is any, if observation is not sufficient for you.

Other hypothetical beings with higher powers of observation may see us {Humans} as living in a small area of a much greater and vaster
Universe with many vectors of space and time
We generally use "universe" to refer to all matter, energy, etc., that exists. I used it in that way in my comment.

2. You say "Motion is a function of time" - I say motion must occur within time - Time is a prime requisite for all that exists.
Time is necessary for
change, not for existence?

Motion is observable within time and is also a measurement of time and can be used to measure time
Motion is used to measure time? Do you refer to mechanical clock mechanisms here? Without the concept of time, motion is meaningless, yes?
