If the earth had rings, would we see them when it was night? It's a stupid question but still

Yes, just as the moon reflects the light of the Sun, the rings also reflect. But perhaps they would not be like the rings of Saturn, they would be smaller because the Earth has the gravity smaller than the one of Saturn to hold them and also they would not be made of ice, because they would be closer to the Sun. There is a specific point in the System Solar known as “ice line” or “snow line”. This is the point in the Solar System, where ice deposits could have survived for long periods of time. Any closer and the radiation from the Sun sublimates the ice away. Instead, the rings could be made of rock and dust.

Earth as viewed from 10,000 miles. In 1969, the Apollo 4 unmanned test flight made a great ellipse around Earth as a test of the translunar motors and of the high speed entry required of a manned flight returning from the moon. A 70mm camera was programmed to look out a window toward Earth, and take a series of photographs from “high apogee”. Coastal Brazil, Atlantic Ocean, West Africa, Antarctica, looking west. This photograph was made when the Apollo 4 spacecraft, still attached to the S-IVB (third) stage, was orbiting Earth at an altitude of 9,544 miles. source
