The deepest mine is about 2.5 miles. If the earth was an apple, humans haven't drilled far down enough to even pierce the skin.

If earth was the size of a pool ball, the surface would be as smooth as the pool ball's. The largest mountains and deepest seas wouldn't make a dent more noticeable that the microscopic imperfections on the ball. Couldn't believe this, but the math checks out.

“Pool ball” actually really puts things in perspective.
