Sorry, Jerry, even won't fly. If deity is necessary to sustain natural processes, then a complete explanation requires that you include deity.
An explanation can be considered "complete" in more than one way. The first way, and the way in which humans use explanations is that the explanation makes sense of all observations, in the context of a given set of initial conditions, or one that can be approximated with confidence. In that sense, even if there is a sustaining deity, our explanation is still complete unless that sustaining deity leaves objectively observable evidence of her action.
In another sense, the one dear to philosophers looking for "ultimate" answers, an event is fully explained only when every factor that contributes to it is identified and explained. This leaves every human explanation ultimately incomplete. Even if we have explained all of the processes that contribute to the event, and somehow are able to exclude the possibility that we have missed a necessary process that leaves no observable evidence, we still have the daunting challenge of accounting for all initial conditions before our explanation can be called "complete." There is no requirement that we care about "complete" explanations in this sense.
What science in general, and evolution in particular says is that the material processes discovered are sufficient as materal processes and no offsite manufacture is necessary.
And when no other processes are in evidence, no other explanations need be invoked.
The real logic [not your strawman] isn't bad, it's just that the evidence won't support the logic.
This is no straw man. You may have been misstating, but this is the logic as you presented it:
You appear to be an atheist in believing that if these material processes operate, then God is absent.
Once again, we conclude that the hypothesis of God is spurious, and
therefore conclude that nature does not require that hypothesis for explanation. We
do not conclude that God is absent from the observation that nature operates.
The logic is that material processes work on their own without the necessity of deity. Unless you believe that, then atheism is untenable.
You have not created a logical sentence. You have given what is either a postulate or a conclusion wihtout identifying which:
"material processes work on their own without the necessity of deity."
A logical sentence would be "because of x, material processes work on their own...", or "Material processes work on their own.... therefore we conclude". You also fail to explain why the atheist position is untenable unless the atheist believes the statement "material processes work on their own without the necessity of a deity." Why would an atheist bother to qualify the statement that material processes work with a statement about a hypothetical entity which atheists do not accept?
Good, then we agree. And notice that you have just admitted that atheism is a faith.
No, we don't.. But I am guilty of misstating, by not clarifying what we "by definition" believe. Actually, it can be restated two ways. The idea as I had it in mind is correctly stated this way:
Atheist believe that the natural processes work on their own without the
need to postulate any necessity of deity to sustain them.
However, it can also correctly be restated
this way:
Atheists believe that the natural processes
can work on their own without any necessity of deity to sustain them. [Where deity is defined in any meaningful way - that is over and beyond the stripped down "sustainer of that which is natural"].
As to your religious world view, I'm not
that curious. I will not pry.
