Explain what electrons do? they seem timeless and all knowing of what other electrons are, and What do virtual particles do? they seem to pop from nothing and have higher energy levels then in our existence of many somethings, and what does Energy do? Perhaps itself is infinite and illimitable? In fact, these are very powerful things and illimitable seemingly and maybe infinite.
But they are not complex.
This is the point of simplicity which I think Rowan is trying to explain.
Before we knew of these things we might think something that is infinite, illimitable, knowing, timeless ---must be complex, but in fact it is very simple, very fundamental aspects of nature.
The point is God is akin to this. It is the very basic. God is the all pervading fabric -not the structures that come to be out of the material in complexity; therefore limitless forms. BUT- out of the material complex structure we can find the consciousness which is a return to the limitless, boundless, infinite, illimitable God.
Why does God have to be supernatural? What if nature is simply an aspect of God? What if the Spirit is an aspect of the consciousness which is the result of the brain and evolution which was inevitable?
What if God doesn't twiddle the knobs and is not complex. God is simple, the simplest form. Not bound by space-time and structure. I guess Rowan and the Agnostic have similar ideas.
The function of something does not have to have complex structure to function powerfully. We know this because of our understanding of nature now and so we know that it is in fact possible for something to be all powerful, illimitable, infinite and yet very simple- not complex.
There is the material and there is the immaterial. The immaterial (GodSpirit) gave rise to the material and the material gave rise to the immaterial (consciousness/soul/spirit).
