Why does earth not have similar impact craters?

Two reasons:

- - We have an atmosphere, that burns away a lot of the material from

anything falling through it to Earth, and completely burns up the small

ones so there's nothing left to reach the ground.

- - When anything does reach the ground and makes a crater, we have

things like wind, rain, sleet, and dust that come along to clean up the mess.

Over time, they fill in the hole and wear down the raised rim of the crater.

We have a atmosphere that burns up the meteors and asteroids before they hit the ground. If they hit the ground, they leave a huge crater.
