I have a minor in Christian Theology, so I did more than read them

.
Keep in mind that we are discussing your comment about necessity for physical bodily resurrection for Christianity to remain Christian, which I challenged. In certain context there is no need to structure the double-standards in interpreting these narratives, because ALL we have is a narrative. Of course, we relate some ordinary everyday narrative as "literal", and some "out there" narrative as an allegory, but there's no solid ground for such dichotomy in religious narrative to begin with. And that's largely my point.
When you read that narrative, you are not reading it to learn historical facts about the past. That's not the predominant reason why this narrative survived to this day. I would argue that you can't really derive any viable facts from it, apart from the overlapping facts that we can verify today, but again, that's not what people read that narrative for. They are largely reading it to fill the gaps in the
unknown.
The problem with unknown claims is precisely that... you can put a multiplicity of concepts in that unknown box and keep it coherent.
For example, we COULD say that God used a story to inspire people's perception of reality and clarify its own character in order to move human development in a positive direction. You would still have a person that demonstrates of what a God incarnate would be like without any need for literal historicity of any of these things actually transpiring.
So, please explain to me why the above couldn't be recognizably Christian at the level of how Christians actually experience and execute Christian beliefs in reality.
Current YEC is fairly close to Lutheran view on YEC, and that's virtually all of the protestant foundation there. Luther didn't get that position out of thin air. There's a steady trend of theological development that lead to that view, and it was a common for various church figures to approximate the age of creation to be within 6k years.
I'm not arguing that Christianity MUST include it, but I do argue that if you are going to go with Orthodoxy, that's a difficult concept to go around. Orthodoxy isn't merely creeds, but also the "unspoken agreement" that didn't need to be consolidated and guarded.
There was no need for disputing things that were in general agreement at that time. The creeds contained beliefs that established orthodoxy and separated the "true believers" from "false believers" in the matters that were disputed at that time.
There were very few Christian leaders at the time who thought that special creation as outlined in Genesis is not literal (in context of special creation of Adam and Eve... the actual people), and that creation is much older than 10k years. That was not the prominent view.
I'm not trying to do that. There are limits to what Christianity could be in context of its own narrative, but it CAN be and actually IS a story when it comes to how people today know about it. Of course, you can distill the story into some orthodox creeds, but these orthodox creeds are not what Christianity is all about... at least these don't have to be.
The reason why I go full-blown deconstructionist is to show you that in context of Christian history itself, the institutionalized version of Christianity is a "filtered shortcut" for interpretation of the narrative. If you view that shortcut as Christianity itself and think that Christianity can't exist without it... then I disagree.
