    The reason is mainly because Earth has an atmosphere.

    Explanation:

    We don't see as many craters in our planet as most of them have been eroded away by wind, water, volcanic activity or any other forces. Earth is also surrounded by an atmosphere which other planets like Mars, Mercury and the Moon lacks. The atmosphere reduces the impact of meteoroids when they hit the surface of a planet as the atmosphere disintegrates them into smaller particles. Also, the atmosphere creates a planet's own weather condition, no atmosphere means no weather. So, planets like Mars, Mercury where there is no atmosphere, there is no weather to erode away the craters. Hence, most of them are still visible on their surfaces.
