The "First Question" is "Exists there a Creator-God?" The reason this is the "First Question" is that all other questions we may ask about reality, and therefore all other answers we may learn, follow from the answer we give to this question.
The question of God's existence is not just a matter of theology -- by the way, I said that precisely that way because these days most people labor under the misapprehension that matters and questions of theology are trivial, that even if a specific question may be interesting, the answer (even if it can be determined) has no importance "in the here and now." On the contrary, understanding the reality, or the non-reality, of God is fundamental to understanding "the here and now;" for the "First Question" is a question about the very nature of reality.
If we answer the "First Question" wrongly, then our understanding of reality must necessarily be incorrect, in contrast merely to being incomplete if we answer the question rightly.
There is only one possible answer to the question: either the answer is "Yes," or it is "No;" but it is not "Both 'yes' and 'no'" and it is not "Neither 'yes' nor 'no.'"
Furthermore, it's not really possible to decline to answer the question; well, not unless one is content to remain an ignoramus (which, as the saying goes, but the Latin for 'agnostic') in all ways and in all things. The reason one can't really decline to answer is because the question is about the very nature of reality. Thus, even those who assert that the question is unanswerable in principle must always comport themselves as though they already know the answer (and, generally, such folk comport themselves as though they know that the answer were "No").
"Exists there a Creator-God?"
I phrased the question that way to a purpose. The issue to be explored is not, "Does there exist some entity which we might reasonably call a 'god'?" (and which may or may not have any connection to us, who live in the world). Rather, the issue is, "Does the physical/material world exist intentionally; is the world a creation?"
See? Just as I said above, the question is about the very nature of reality, and the anwser is one or the other, either "Yes" or "No."
And everyone lives as though he knows the answer.
In this post, I am not going to answer the question. Of course, if Gentle Reader knows that I am a Christian, then he has a really good idea of which answer I will give as correct; though he may not yet know the why of it. However, the point of this post -- and any discussion which may arise from it -- is not about the answer, but is rather about the question. So: no answer from me at this time.
