Unfortunately, we haven't found many very old rocks on Earth because our planet's surface is constantly renewed by plate tectonics, coupled with erosion.

Hello from above our magnificent planet Earth.

We may have had a 10th and 11th planet that collided. It's also possible that the outward migration of Neptune scattered comets and small planet bodies, inducing collisions in the asteroid belt. The close passing of a neighboring star could have had a similar effect.

We love our planet Earth. We should - it is our home, and there's no place like home. There can't ever be a better place than Earth.

Nobody rules the world.
We may take care of planet earth
as a harmonious part in our universe.
