Enki seems to have understood and has extended the argument in a non monotheistic direction and has done so without abuse.
......Don't you wish your atheism was hot like that?
I have only tried to understand your position, which to me seems to be some sort of rephrasing of the old 'first cause' idea. That does not mean I support it at all. I suppose if there were such things that we could class as non derivable, present scientific thinking might suggest such things as sub atomic particles were the nearest we can get to this. I'm not sure, however, where you think this leads to, and, in any case, I would be loathe to use your language(e.g. non physical, actual) as I find it far too vague. For instance, When I think of gravity, even though it has not been fully explained, I see it as entirely part of the physical universe. How does the idea of derived or actual fit in here?
And this is leaving aside the questions relating to the formation of new attributes, which may 'derive' from a combination of other things, but are nevertheless new, in that they are not present in those other things in isolation.
I think a lot more clarity is needed on your part.
