  1. It would take light a bit over a second to travel from Moon to Earth, while sound would travel the same distance in 5 minutes (same distance in Earth's atmosphere)

  2. Sound actually travels rather slow, only 340 meters per second. Look up videos of people firing at steel targets at ranges over 150 meters: you would see the target move from impact, and after a split second hear the sound.
