I am saying that their conception of God is logically inconsistent, and cannot exist. But I am also saying that something which has some of its characteristics could exist.
So what do you think are the base characteristics that would allow God to exist and still qualify as a God?
I am not saying this. Unlike Augustine, I have the benefit of the past 500 years of science and philosophy to help me. No modern philosopher can be compared to Augustine for this reason. It's not a level playing field.
I don't see how science affects Augustine's arguments at all. As I seem to remember he proposed something along the lines of evolution in any case didn't he?
If they are physically impossible then they are logically impossible with regard to actual realities that really exist. If something cannot physically exist, then it cannot exist in our world.
If God is defined as creator of the world then he must be ontologically
prior to the world.
So in creating the universe God cannot have been bound to what is possible in that Universe. That does not make a shred of sense.
God could define what is possible. Could define a physics to allow perpetual motion machines or anything he pleased.
Logically possible and physically possible are two different things.
No, it really is impossible. A good example is the Wollemi Pine, which against all the odds has survived since 93 mya. But it survived not by adapting but by being in exactly the right place and avoiding death by perpetual coppicing. It evolved when Gondwanaland was on top of the south pole, in conditions of almost permanent twilight. When Australia drifted north and got hotter/brighter it was wiped out by faster-adapting true pines and flowering trees. But in two deep gorges with very low light levels it has hung on, not by apadting but by sending up more and more trunks from the same root system and not giving up its place on the gorge floor. When individuals in a species opt for near-immortality as a survival strategy then all evolution must grind to a halt. The wollemi's are dinsousaur food. The point is that it is a logically entailed by this strategy that evolution is halted. You cannot be immortal and genetically adaptive. These things are logically incompatible, not just physically impossible.
Let me repeat - the fact that it does not happen in our case does not make it impossible.
In the case of our biology adaption depends on replication. Adaptation happens when errors occur in the copying mechanism and the consequent physical change provides an advantage.
Is it really impossible to conceive that if there is life elsewhere in the universe it does not depend on DNA?
Again, was God limited to one particular biology when he created the Universe? If so then what was it that defined the biology he was limited to?
Does adaptation logically have to depend on replication error? Can you show that the idea of a physiology of adaptation without replication is contradictory?
And again, is adaptation really necessary for the creation of a sentient agent? Is trial and error the only tool available to a being with all power over existence?
If God could have nudged evolution he could have created a human being from scratch. Or any other kind of being. Or any kind of universe.
Or he would not be God.
No, the natural processes are the natural processes. I never said they were God.
You appear to be saying that God is logically bound to what is possible within those natural processes. For example that God had to use genetic mutation and natural selection to create a sentient being.
If God is defined by the natural processes, then they are ontologically prior to God and by definition it is those processes that are God.
