Mars, Venus, and Earth were geologically active longer than Mercury and the Moon. This means that their surfaces underwent processes such as erosion, volcanic activity, and tectonic activity that "erased" many of the craters that may have formed. In contrast, Mercury and the Moon are small and have cooled down faster, so they have been geologically inactive for longer, leaving them heavily cratered.
