The cratering of the Moon was done in it’s early days. The Moon didn’t intercept Shoemaker-Levy 9 in 1994. Jupiter did. had it not we would have been obliterated.
So you know when the last time the moon took a hit that otherwise would have struck the Earth.
Since recorded history is all of 7000 years I think you are making a reach far beyond your grasp.
Shoemaker-Levy 9 in 1994 was on a collision course with Earth, if Jupiter had not been in the way? I’ve not seen that stated anywhere. Do you have a (reputable) link?
Googling this, I found a couple (rather shaky) sources indicating that a collision with Earth was possible somewhere down the line, but those were initial calculations and were revised once Shoemaker-Levy 9’s orbit was better known. Granted, who would take Jupiter out of the equation?
I’d also clarify: MOST of the cratering of the Moon, as Earth’s, occurred in it’s early days, but not all of it. However, it is probably correct to say that the Earth protects the Moon more than the Moon protects the Earth (until we build an asteroid defense station on the Moon, anyway!)
