It is only through your godless materialism that you discount, a priori, the Angelic Push (AP) theory of gravity, which posits that gravity is really Angels pushing things here and there. AP theory is scientific! Teach the controversy!
I like it. Think out of the box! Don't be afraid to explore alternative theories. Stop the censorship!
"It is only through your godless materialism that you discount, a priori, the Angelic Push (AP) theory of gravity, which posits that gravity is really Angels pushing things here and there."
Apparently you missed my point entirely. The point is that gravity is an equation, and the equation is the same no matter what theory is attached to it, be it your comical angelic push, some sort of laws of attraction, or mass warping space.
The equation for gravity is experimentally verifiable -- the reason for the equation matters little except influence possible future directions.
History, however, is full of unique events. Because of their uniqueness, it is impossible to test historical theories the same way you can test scientific theories. Therefore, they are based more on philosophy than experimentation. The history of the world that includes universal common ancestry is based on naturalistic assumptions.
