The second densest moon in the solar system which has been floating there for all of recorded history and most likely a lot longer based on the movement of the planet (you'd think they'd get bored at this stage, have they nothing better to do) is really an alien space ship.
Titanium is mostly located in the Earth's crust right (do correct me if I'm wrong on this one) so if the theory on the moon being the result of some planetary impact is correct then the reason for large deposits of titanium on the moon is that that's where a large amount of the Earth's crust ended up.

The titanium isotopes, precisely match earths titanium and not even a spread of meteorite titanium.
