Nope he did not refute my statement that gravity is a fact with tons of observation behind it and that evolution has never been observed:
For a supposed astronomer you do not even know your terms. It is called the LAW OF UNIVERSAL GRAVITATION it is far more than a theory. As I told physicist, by denying something which you know to be true you are being dishonest. If you are a radio astronomer you know that gravity has been observed. If you do not know it, then you are not a radio astronomer, so either way you are being dishonest.
What he did do was go into a long history of the theory of gravity which is totally irrelevant to what the discussion was about. This is the typical tactic of evolutionists - go into a long description of something that is true but not to the point and call it a refutation.
No one has "seen" gravity, either. The best we can hope for is to observe the effects of a particular force or influence...either by getting bonked on the noggin by an apple, or by uncovering the fossil remains of progressively more complex organisms.
