Uneven Cratering of Moon's Surface

I read about how one side of the Moon is more heavily cratered than the other.

What would explain this unevenness?

This is just a guess, but the moon orbits us so that we always see the same side. The side facing us should be less cratered as the earth offers it some protection from hits.

Its not so much uneven cratering; 'our' side of the Moon has suffered the massive Maria forming events where as the farside did not.

This is a real mystery.

Although the Moon was closer to the Earth in the past it could not have been so close for the Earth to physically protect it as a shield, because that would require the Moon being well within the Earth's Roche limit and it would have broken up.

There is a second mystery here - the same is also true for the Earth; we call the Earth's Mare the Pacific Ocean! In the past it was even bigger as the land masses were all one continent - Pangea.
