W/o an atmosphere to erode them, they stay fresh.
because scientists now know the age of the moon, they can count the number of impacts craters to find the rate of the cratering science the birth of our solar system. by knowing the rate of crating, scientists are able to use the number of the craters on any body of water to estimate how old the body of water is. this is easier because sceintsts don't need to bring back the rock to find out.
The craters are preserved as there is nothing to erode them.
On bodies without atmospheres, such as the Moon or Mercury, craters are subject to little to no erosion or weathering. This means that once a crater is formed by an impact, it can remain relatively unchanged for billions of years. The lack of an atmosphere also means there is no wind, rain, or other processes to modify or erase the craters over time. Consequently, the surfaces of these bodies can preserve a detailed history of impacts.

Earth is the only planet in our solar system known to have large bodies of liquid water on its surface and a protective atmosphere that allows life to thrive.
A space telescope such as the Hubble Space Telescope can view heavenly bodies clearly without the filtering effect of Earth's atmosphere. These telescopes orbit above Earth's atmosphere, providing a clear view of objects in space without distortion or interference.
Meteoroids are small rocky or metallic bodies that do not have an atmosphere or surface water like larger celestial bodies such as planets. However, when a meteoroid enters Earth's atmosphere and burns up, any water present in the meteoroid can be released as part of the vaporized material seen as a "shooting star."

Without gravity, objects would not be pulled towards the Earth, so there would be no tides, no atmosphere, and no orbits of celestial bodies. Anything not directly tethered or attached to a surface would float off into space.
Earth's surface comprises the lithosphere (solid outer layer), hydrosphere (water bodies), and atmosphere (layers of gases).
