However the materialistic creation story of atheism, obviously doesn't need to assume a supernatural realm which might make it more parsimonious in that regard which I would concede. However, how many more assumptions/entities/variables, must be assumed in order to accept materialism?
First Mike, there is no such thing as the materialist creation story of atheism.
Second, there are almost no assumptions in the conventional theories of Old Earth or Evolution.
No really need to stop posting supposed refutations of claims no one makes; it just makes you look silly.
