If the ages of Earth and MOon are nearly identical...why are most rocks found on the Moon so much older than Earth rocks? Can you answer this question for me? Thank you very much.

The rocks on the surface of the moon erode very slowly since there is no atmosphere and no plate techtonics. On the surface of the earth, erosion and techtonic processes have changed the surface so rapidly, that we do not have rocks on the surface of the earth as old as rocks on the surface of the moon.

Two big things I think contribute to this. The earth is still continually making new rock at the surface, i.e. volcanoes, but the moon is not.

The other thing is there is no life, little atmosphere, and no fluid water on the moon, but on earth there are these, things which break down rocks by erosion and other processes as well as bury them under layers of soil.
