With all due respect, the terms below are not meant to be disrespectful. I know you are already intelligent enough; but I must present the seemingly obvious positions are are presenting:
I appreciate the civility. We are having an online discussion, so I wouldn't likely be insulted even if you did it with an insult in mind. But civility is always refreshing in this context, so I appreciate it.
I think before you get too carried away with logical fallacies, we should talk about a couple of things:
1) Logic is not a study of fallacies and how to identify these. It's very typical to see when someone who never studies formal logic, or has discovered a few informal fallacies begins throwing these around as some kind of "foul" that supposed to suspend the argument.
2) Virtually all of the fallacies ever invoked in this context are informal fallacies. What you need to understand about those is that claim of informal fallacies is a kind of "reasoning by analogy". These amount to a claim that an argument is defective because it resembles in some paradigm case of a defective argument. These can be helpful and persuasive, but the reality is far more nuanced than reasoning by analogy can tackle.
The reason why I don't invoke informal fallacies in my arguments, is because I perceive it as sign of intellectual laziness. Some people erroneously think that they can shut down an argument crying "foul" without need to demonstrate why and how they see this claim of fallacy is applicable in this context.
So, Can you do me a favor? Next time when you are tempted to pull out the "fallacy card" ... can you instead tell me why you think my reasoning is false. It would be much easier discussion to have.
'The term God-of-the-gaps fallacy can refer to a position that assumes an act of God as the explanation for an unknown phenomenon, which is a variant of an argument from ignorance fallacy. Such an argument is sometimes reduced to the following form: There is a gap in understanding of some aspect of the natural world.'
'An argument from ignorance (Latin: argumentum ad ignorantiam), or appeal to ignorance ('ignorance' stands for "lack of evidence to the contrary"), is a fallacy in informal logic. It says something is true because it has not yet been proved false.'
What you wrote above would be a very good example of of misapplying informal fallacies with claim that these invalidate or applicable to the argument.
I'm not claiming here that because we don't know therefore God
I'm claiming that our reality is void of objective meaning unless we presuppose God. These are two different claims.
I strongly advise you watch the 2 hour documentary regarding Kitzmiiler vs Dover: Intelligent Design on Trial. Then tell me again how you can lump or smuggle in all your other topics in with theology
Ok, I'll explain, because you are clearly unaware of the issue.
Mathematics, law, and Biblical theology can all argue in context of "proof" via clearly-defined presupposition framework.
In science, for example, there are no appeals to logical proofs, because science doesn't work via true/false binary means:
See here.
Common misconceptions about science I: “Scientific proof”
If you are going to reject the basic concept that humans exist and write stuff to paper, as the baseline, then I guess we have nothing further to discuss...
I don't reject that humans exist. I'm not sure where you are getting this from. I presuppose that God exists as a necessary precondition for objective meaning.
And again, you do might understand what two fallacies you are committing...
Which fallacies would these be?
Again, Can you do me a favor? Without saying or naming these fallacies ... tell me why my reasoning is false. It would be much easier discussion to have.
Again, same two fallacies..... Meaning, therefore Yahweh?
We are going in circles... It's one thing to appeal to a 'first cause', first mover', 'prime mover', 'timeless mind', other... However, when reading the Bible, it does not appear to fit with even your model. One has no choice by to deny, distort, and redefine many statements and assertions, to make the Bible fit with known reality.
In this thread, I started with slavery...
No. You don't understand the claim, and you keep implying that informal fallacies are absolute

.
Reason of itself is a circular concept, because you would need to validate reason as a concept before you can assume that something is reasonable. And what would you use to do that other than reason? It's circular, but it doesn't mean it's invalid.
I'm not saying reason therefore God. I'm saying... "God, therefore reason", in context of examining presupposition models.
To help you out... I'll reword it as:
1) IF we assume that God exists... THEN our model assumes that objective meaning exists in reality
2) IF we assume that God doesn't exist ... THEN our model assumes that there is no objective meaning
I'm not claiming here just because reason and meaning exists, then God must exist. I'm saying that given two presuppositions above, we build two different models of reality, to which #1 is a better fit for my worldview, because it justifies me acting in a way that presupposes that there is objective meaning in reality.
If I take on #2 model, it means that I presuppose that there is no objective meaning, and reality is arbitrary, and I'm not saying it alone. It's actual conclusion that naturally follow that model.
Hence, in such reality... all meaning would be subjective.
