Further utterly foundation-less assumptions. Even if it were proven that the planets are all captured ( which it isn't ), then why would the density be the same for all of them? That's just so hideously wrong it's not even funny Jerry. You're making utterly unjustifiable assumptions simply to fit your model. What you should be doing is looking at the DATA and then working from there, not cooking up a model, and making up the data to fit it.

And again - please explain why you believe the 'average' density of the Earth and the Moon is an accurate figure in any way whatsoever? Why should the moon, a tiny body in mass terms compared to the Earth contribute half the density figure for the Earth Moon system. It shouldnt. You've just made a figure up so it fits your graph. THAT IS NOT SCIENCE. STOP PRETENDING IT IS.
