The destruction of the Moon would be detrimental to life on Earth due to the resulting debris field.

“the energy between the pieces breaking up and hitting each other would destabilize their orbits and they would end up crashing into the earth and that would be bad very very bad as we know happened to the dinosaurs”

Earth's lack of visible craters compared to the Moon is due to active geological processes like plate tectonics, weathering, and erosion.

“because like I said the earth is very geologically active we have plate tectonics that's causing the plates to subduct underneath each other you essentially erase the history of what has happened in the past on earth”
