Statement 2: The atmosphere rotating with the Earth means there is no strong wind resistance or relative air movement caused by our speed, which would otherwise make the motion noticeable.
Statement 3: Without nearby stationary objects or objects moving at a different speed, we lack a visual reference frame to perceive our rapid motion. Distant celestial objects are too far away to provide this sense of rapid nearby movement.
