It was a little bit of a joke. The bigger body with the deeper gravity well will get more hits.
To say that the Moon protects US is a bit like saying standing behind a fire hydrant would protect me from a tidal wave.

Everything in the heavens is perfect. (You could get burned at the stake for saying otherwise, ask Bruno if you don’t believe me)
