Lunar crater origin

It is generally accepted that the lunar craters are formed from meteroic 
imnpacts.

Consider Crater Ptolemaeus - a large crater in the near middle of the 
lunar image viewable from the earth.

There is one small problem - the meteorite which created this crater would 
have also have had to pass through the earth prior to impact on the moon.

Any views on this problem ?
