The vast majority of space rocks crashing down towards Earth is vaporised into dust by the immense temperatures generated by the friction with the atmosphere. Pieces rarely reach the Earth’s surface and they’re usually tiny if they do. That being said bigger meteorites do impact the Earth, like the one in Russia a few years ago, usually though they fall into the ocean.
There are craters on the Earth too, it’s just that most of them are not easily visible since they’re usually overgrown with trees and plants. By contrast the moon has no atmosphere or an active eco system so not only does it get a lot more impacts but all the craters are very easy to see.
A lot of people are mentioning the Earth’s atmosphere here, and it just isn’t that big of a factor for *sizable* impactors over history. Yes, it keeps dust-sized particles from making a constant stream of micro-craters, and stops the fist-sized rocks from making small craters, but even Venus with 90 times Earth’s atmosphere doesn’t stop any craters bigger than about 2 km from being formed.
Okay, we wouldn’t be seeing many craters bigger than the atmospheric cutoff being formed *today* because the influx of such objects is currently very small, but if we could have had the protection of our atmosphere while somehow turning off erosion/volcanism/tectonism for the past 4.5 billion years, then we would look (from a distance) as cratered as the Moon does–only when looking at small scales would we notice the difference.
Earth has an atmosphere where lots of that stuff burns up.
The moon doesn’t.
Also there is erosion and weathering happening on the Earth. That’s not happening on the moon.
Earth is full of craters. Some may argue half of it is a huge crater : https://www.esa.int/ESA_Multimedia/Images/2010/04/Earth_Explorers_The_Earth_s_true_shape
