Why does the moon have so many craters when Earth doesn’t have, even though Earth’s gravity is stronger and it should be the one attracting the comets?

Atmosphere.
It serves two purposes.
1. Objects burn up in it and as such are less likely to impact thus when they strike earth they are less likely to make it down in one piece if they make it down at all therefore fewer craters are formed.
2. Erosion. The earth does get hit. quite a bit over the history of the earth but our atmosphere allows us to have wind, rain and plant growth etc… which all erode craters over time. The moon doesn’t experience erosion so a footprint in soft dusty moon soil from 100 years ago will still be there today just like even a tiny crater from an object the size of a penny hitting the moon a thousand years ago will still be there today where that same footprint and same crater would have long since been eroded away on earth due to wind, water, plant growth etc…
