Mercury looks a lot like Earth's Moon. Why do you think it does? Both have been struck by a lot of asteroids. Both have no atmosphere, so there is no weathering and erosion. If they had an atmosphere, many of the craters would have been eroded away. Both have no plate tectonics to transform the landscape. This would also remove a lot of craters.
