In fact, the "night sky" has not been "lit up" much. The "night sky" is mainly dark, because the background is very dark, so you can see many stars. Unless you have a pair of cat-like glasses, you should be bright at night. During the day, those stars won't disappear, but their light is too dim, so we can't see them. Because we are not too far away from the sun, we only need a sun to illuminate our "daytime", which is far better than the night sky. As for the night sky of the whole galaxy, it has never been "bright".

Of course, writing such a composition is worth 0 points. This subject needs to be investigated. It wants you to demonstrate through metaphor that many hands make light work, that's all.
