These are all interesting points, however someone like John Walton if I'm not mistaken is the one who popularized this ANE hermeneutic and I don't see any young earth creationists adopting this method. It seems that the only logical conclusion is that if Genesis 1-11 is only meant to be interpreted spiritually then we are left with no information about the beginning. How do we know Adam and Eve really existed then? If death of living creatures happened before the fall, then the door is open to evolutionary assumptions. I would say the main thrust of the argument is that Genesis 1:6-7 does seem to be describing something hard to understand. But how can I be certain it's speaking about a solid dome that everyone in the ancient times would know to be a reference to flat earth cosmology? Supposing the Pentateuch was written in the 15th century BC, I'd have to know the culture of that time which I know nothing about.
John Walton popularized "the" "ANE hermeneutic" ?
I guess that may be partially true. He is accessible because he is on social media. But his views are not unique, nor did they originate with him. His ideas really are just of a larger scholarly consensus. Ancient Near Eastern Texts have been gradually discovered over the past 150 years or so. Consider how long the dead sea scrolls have been around for example. The hermeneutic may seem "new", but thats only because ancient near eastern artifacts themselves, and their discovery, is somewhat "new". At the same time however, the dead sea scrolls are quite old. YECism also may seem, at first glance "old" or the historical and traditional way to understand the text. But as we can see, YECism is actually largely influenced by modern science via scientific concordism. As you are likely seeing in the resources that I have been sharing.
As far as I am aware, almost no Bible scholars deny ancient near east context of the old testament. And YEC appear to be a minority as well.
And acknowledging ancient near east context of Genesis doesn't mean that Adam and Eve didn't exist. It doesn't mean to interpret the text "metaphorically".
The goal is to simply understand the text as the authors wanted the listener to understand it.
If the authors thought earth was not a sphere (because that wasn't discovered until perhaps 600BC or so), then when they say "a flood covered the earth", we have to understand what that actually means, as they would have seen it.
It doesn't mean that the history they describe isn't real. It just means that it may not look the same as what is immediately assumed in our context.
And that's absolutely correct, in order to understand the passages that may currently seem difficult to understand, requires.....
Work.
I know. Its disappointing. The Bible takes work, to understand.
And that's why the church is having such a hard time today. The evangelical church in particular. Because many in the church, quite frankly, don't want to put in the work to read about the ancient near east historical background of the Bible.
But no worries! Because many Bible scholars have actually done a lot of the work for us already.
What was once thought to be a difficult situation, turns out to be not so bad if we know where to look.
I would recommend the "NIV application commentary series" with consulting editors John Walton and Tremper Longman III.
There are many short and simple books on the subject such as:
John Waltons:
Lost World of Genesis 1
Lost World of Adam and Eve
Lost World of the Flood
Micheal Heiser's:
The unseen realm
Reversing hermon
Ben Stanhope:
(Mis) interpretating Genesis
Miller and Soden:
In the Beginning...We Misunderstood
Seven Days That Divide the World: The Beginning According to Genesis and Science” by John Lennox
Reading Genesis 1-2: An Evangelical Conversation” edited by J. Daryl Charles
Four Views on the Historical Adam” edited by Ardel B. Caneday
Death Before the Fall: Biblical Literalism and the Problem of Animal Suffering” by Ronald E. Osborn
Reading Genesis Well by John Collins.
Among others. There are actually many resources available. There is also a Facebook group known as "Answers to Answers in Genesis" that I would also recommend for casual conversations.
