They do move… its just incredibly slow when compared to the objects moving around you.

Next time you’re in a car or bus driving… look out into a field. The closer an object is… the quicker it speeds by, the further out it is… the slower it moves.

However that being said… its moving slow to where we are in our own galaxy. If you were to go there and stand on a planet and look back at us… you could say the same thing.
