When you look at pictures of other planets, their surface seems to be made up of a huge collection of craters (which I imagine are from meteorites). Planets such as [Mercury](https://cdn.mos.cms.futurecdn.net/PFQ97KNjjTebMzenT3GeKd-970-80.jpg.webp), [Venus](https://scitechdaily.com/images/Venus-Global-View-Magellan-Mapping.jpg), [Mars](https://images.newscientist.com/wp-content/uploads/2016/07/19111442/pia00407.jpg?width=800), [Pluto](https://img.welt.de/img/wissenschaft/weltraum/mobile147668745/7032502177-ci102l-w1024/Zwergplanet-Pluto-2.jpg) (yes, not a planet) and even closer to home, the [moon](https://img.welt.de/img/wissenschaft/weltraum/mobile147668745/7032502177-ci102l-w1024/Zwergplanet-Pluto-2.jpg). But when you take a look at the [Earth](https://images2.fanpop.com/image/photos/9400000/Earth-Wallpaper-planet-earth-9444615-1024-768.jpg), no craters are visible. Why is that?

Mostly because we have water. Water covers up a lot of land. So the impacts are just not visible. Water also erode. Impacts that existed simply get washed away.
