You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
When looking out the window, if you focus on a distant building outside the train, it may appear that the train is not moving because the building is not changing position relative to the train. However, if you look at a nearby platform or another train beside yours, you may notice the train's movement compared to these closer reference points, making it appear that the train is indeed moving.
