We don't have proof of what the moon in bulk is made of. We have proof that there are a few small pieces of material that were removed from the moon by astronauts that turned out to be rock. The rest could very well be green cheese. We have made a completely and utterly unjustified extrapolation based on incomplete evidence. There is no proof that the ENTIRE moon is made of rocks. In fact, the rocks were probably fakes planted on the moon by the evil atheistic "moon rockers" to bolster their failing "moon is made of rock" theory. Any of this starting to sound familiar?
