1. Should it mean that anything we would create does not exist in
reality?

2. Isn't an orbit just a "device" we created?

3. Can you point a reality object "Earth orbits Sun"?

Rather the opposite view would be unphysical.

How does it matter? The physics of the Unverse does not depend on the
frame of reference. This is the fundamental fact of Einstein's theory.
Are you or your chair going to prove otherwise?
