Why are pictures of the Moon, Saturn, Mars, etc covered with craters, big and small???
We don’t see them on Earth....Is it because we have an atmosphere that creates weather and continually changes the surface? Plus plant growth and shifting sands cover what was there??
Since when are pictures of Saturn covered with craters?
Yes, but ... they definitely do exist on earth, but the smaller and older they are, the more they've been eroded away.
Over billions of years, geologic activity on Earth erases impact craters. Its the same reason you dont see any impact craters on Jupiters moon Io, which is the most geologically active body in the solar system.
What we see in the sky is painted on backdrops like any studio has. Some god child has built a diorama and we are the display for their 3rd grade class project.
