They last forever.
rayed craters
They last much longer than that. Some of the moon's craters are billions of years old. They last so long because there is nothing to erase them. Earth has wind, water glaciers, volcanoes, and tectonic plates to bury, erode, and erase craters. The moon has none of these processes. Some refer to the moon as geologically dead.
because the gravity keeps it there and there is not or is an answer for the time in space to know how long it stays there
Asteroids hit it a long time ago

Water causes erosion, it washes things away, slowly or quickly, so craters do not last as long on a world that has at atmosphere and water as they do on the moon, which has no atmosphere and no water except for some ice in certain polar craters.
Craters last for millions of years on the surface of the moon because the moon does not have an atmosphere. Saying this the moon does not have anything able to fill in the craters such as soil or rain.

Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
yes, the earths craters were made a long time ago. Some craters are volcanos. They just pop up

Craters, mostly. The new Messenger photos of Mercury from just last week show craters on craters, and chains of craters. It looks a lot like the Moon, actually. You can see some photos of Mercury at the link below.
