Assume, the Earth is not spinning. The only explanation for the change of day and night could be described through Earth orbiting the Sun (at a very large speed, so 24h for one rotation around Sun). Or, of course you can assume that the Sun is orbiting the Earth, again 24h/rotation. If this was the case, we would not experience the change of seasons, because they would be “replaced” by day/night change. Also, the stars at the sky would stand still.
