That depends on where the crater is, and how it formed. Meteor craters on the Moon or Mars? Nothing generally fills them up, and lunar craters are still visible after many hundreds of thousands of years.
On Earth? A meteor crater will, eventually, fill with dust or dirt and water. A good number of meteor craters are visible as circular lakes. The Meteor Crater in Barringer, AZ is still empty after 50,000 years.
Volcanic craters sometimes fill with lava, or with dirt and water. Crater Lake in Nevada is a .... lake, filled with .... water.
They erode through wind and rainfall, the rim gets worn down and the center depression fills up.
Nothing. There is no air on the Moon, so the craters contain nothing but a little dust and some rocks; not much at all.

Nothing burns up craters before they hit earth.

yes, the earths craters were made a long time ago. Some craters are volcanos. They just pop up
Water dissolve things and fills up cells
The craters are named after seas because scientists believed in the past that they were dried up oceans.
Space rocks. On Earth we would call them "meteors", because they would generally burn up while passing through the atmosphere. The Moon has no atmosphere, so there's nothing to prevent small space rocks from crashing into it. This has left the Moon covered with millions of craters; big craters, little craters, craters IN craters, and craters ON craters.

The moon has plenty of craters, many of which can be seen from Earth, with a good telescope or binoculars. The craters are there, because the moon has no atmosphere for the objects to burn up in, so all of them hit the moon.
