Yeah I remember wondering in grade school how they could be so sure that meteors didn’t hit the Earth anymore when looking at the moon you can see the huge craters from 180,000 miles a way.
The best answer I ever got from a science teacher was to answer my question with the question; “If we knew a meteor was going to hit the Earth why would we want to know?”
They told us the Moon was there to shield us from meteors.
Riiiiiight...
