Ever wonder why the moon has so much holes?

A celestial being in space is allergic to stars; her allergic reaction causes her to sneeze varying sizes of particles called "asteroids." Those particles are the holes in the moon. Similarly to our germs when we sneeze, some roam floating in space. But her celestial boogers are much powerful- they don't simply go away in thin air, it continues to roam until it reacts with another object in space.
