1) Because of earth zipping through space around the sun at 66,622 mph (107,218 km/h) Mean Orbit Velocity. At 65 mph on a highway, I would have to rollup all the windows for the air inside the car to be calm and 'come with me'.
2) The model of an atmosphere adjacent to the vacuum of space also demands a firmament.
