For the others, one can only use relative age dating (such as counting craters) in order to estimate the age of the surface and the history of the surface.The biggest assumption is that, to first order, the number of asteroids and comets hitting the Earth and the Moon was the same as for Mercury, Venus, and Mars. The bottom line is that the more craters one sees, the older the surface is.When we age date a planet, we are actually just dating the age of the surface, not the whole planet.
