I imagine the source can be found wherever they dated the surface dust (older) and the rocks (younger). Perhaps NASA or some independent labs. You’ll have to look around on your own - sorry to inconvenience you with doing your own research.
So, you make a statement totally at odds with mainstream planetary astronomers and geologists, claiming that the Moon was actually formed billions of years earlier than the Earth, and CAN'T cite a source.
So, according to your logic, you can make all the absurd claims you want, and unless I can to the legwork and find your UNIDENTIFIED sources, your statements stand?!
But I guess all I need to do now is google "older surface dust" and "younger rocks," and I'll find it myself, you say?
See my tagline!
