Question

If the Moon was bombarded, wouldn’t the Earth be as well since they are very close to each other?

Answer 1

Destroying the Moon would send debris to Earth, but it might not be life-exterminating.If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
