After they hit the ground.
The earth is not covered with impact craters because weather and geological activity erodes the craters away over time.
Yes there are craters, and yes some of them are very deep. All craters, however, do in fact have a bottom. A bottomless crater would actually be best described as a "hole," and there are no holes through the Moon.
Asteroids hit it a long time ago
Craters on the moon are not volcanic, they are impact craters.
Galileo discovered that between the moons night and day sides the top was sometimes irregular and sometimes the bottom was smooth. He realized the irregularities were because the mountains on the moon.

Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
