Imagine you have a bunch of little helpers in the sky that help you find your way, tell you what the weather is like, and let you talk to people far away. If all those little helpers suddenly disappeared, we wouldn’t know where we were, couldn’t check the weather, and might not be able to call our friends or family anymore. It would feel a bit like being lost in a maze with no map.
Examples
- If all your toys stopped working at once, you wouldn’t know what game to play or where to go.
- Without a map, it's hard to find the way home.
