Why Is There Light On Earth But Space Is Dark?

There is light on Earth because we are close to the Sun, but space is dark because it’s very far away from the Sun, like being in a big room with only one tiny lamp.

Imagine you're in a big, empty room. At one end of the room, there's a small lamp. When you stand near the lamp, it feels bright and warm. But if you walk all the way to the other side of the room, the light seems much weaker, almost like it’s not there at all.

That’s what happens with Earth and space. The Sun is like that tiny lamp. Earth is close enough to feel its brightness, so we have light during the day. But when you go into space, you're far from the Sun, like being on the other side of that big room. There’s still light, but it's much weaker and spread out, so space feels dark.

Also, Earth has a blanket of air that helps keep the light around us, while in space, there's no air to help carry the light, it just goes straight out into the darkness.
