I don't get your point. I can set my fix reference point for the motion everywhere I want, even some random point in space. It doesn't change anything.

It just looks weird if you put earth stationary and let everything else rotate in spirals.

I mean, you can look at it like that, but what do you gain?

Movement is always relative to some other point.

If you jump from a building, it doesn't change anything if you move towards earth, the earth moves towards you or if you both move and meet middle way.

You can't tell the difference.

Its proof to me and that is all that I need.
