Autodidact ( and more or less Mac's and ethos),
This is a very old question. This issue has been debated as much as creation vs evolution since the 1960s in scholarship. There are hundreds of peer-reviewed papers, rejoinders, commentaries and MA Theses and PhD theses on this stuff--not to mention YouTube debates and interviews. It's not new.
Therefore, if you (i.e. Autodidact specifically) seem to spend so much time on biblical cosmology as we have already exchanged via email, read the relevant expert literature on this matter and become an expert yourself. I myself spent several years on this stuff and I think Im satisfied with my view of it now. But, this whole issue of biblical cosmology and Inspiration is a big can of worms and no answer in this forum will ever really answer your question(s) because it's far more complicated than just one verse here or one verse there. The entire Bible is filled with non-scientific language--it's not simply cosmology. The Bible reflects ancient Near Eastern and Greco-Roman concepts and worldviews. It's normal that if you take Inspiration and Innerancy out of one passage (2 Tim. 3.16) and you then mix it up with all sorts of issues that the authors were not concerned with, you then run into these problems, and we've all been there in scholarship. The points you guys made in the comments do not answer the question at hand.
My answer (which is based on scholarly research) is that the OT reflects the ancient Near Eastern worldview in cosmology, numerology (3, 7, 12, 24, 70), physiology, zoology, sexual reproduction (seed / bosom), etc, and the NT reflects the OT and Greco-Roman worldviews. It's normal. Remember that Abraham came out of Ur in Mesopotamia and Moses out of Egypt. The Hebrew text is filled with Babylonian, Assyrian, and Canaanite concepts and linguistic cognates. It's normal, they lived there at that time! They were surrounded by them. God spoke to them so they could understand and the authors described and spoke in the language they knew with the concepts they knew ( look at the Tabernacle and the Temple--filled with Edenic and ANE concepts). It's inspired at the Message/messages level, not at the scientific level. Therefore, yes, the biblical authors believed there is water (a heavenly ocean, NOT vapor) above the solid (raqia) sky/dome. But, in real reality, it is not like that. The earth and the sky and space is how we see it in Google Earth, NASA. Therefore, in real reality there is no ocean and the sky is NOT solid. I already know you disagree with my previous sentence, since you are a flat-earther primarily because of the Bible and Inspiration (secondarily because of some scientific understanding that you became convinced of--Im not going to challenge you here since Im no scientist, Im an exegete).
The biblical text does not need to be scientifically accurate for Inspiration and Innerancy to work. It's a false cause and a false assumption. If you think that resolving this cosmological matter solves the Inspiration issue, please reconsider. There are a whole bunch of other similar issues throughout the entire Bible--it's not just cosmology. For instance, off the top of my head, Luke CORRECTS Mark's Greek. Mark's Greek is not as smooth as MAtthew's or Luke's and they both change Mark's Greek when it's off. It's not God nor the Holy Spirit that made a mistake in Mark at the language level, it's Mark! But Inspiration has nothing to do with this! It's a common false cause.
Please start reading this famous paper that all scholars who specialize in this quote and cite in their academic papers. Then, google and read all of Paul H. Seely's papers. Then, compare that with other rejoinders and refutations online that are peer-reviewed. Then, you will start to understand little by little how it works. It takes months and years. You will not be convinced nor satisfied by just googling here and there once in a while.
2 resources for you to start academically on this matter:
Paul H. Seely
THE FIRMAMENT AND THE WATER ABOVE
Part I: The Meaning of raqia in Gen 1:6-8
Start with this paper from Seely and then google other papers from him. You dont have to agree with everything he concludes, but he makes some really good points that lots of Hebrew scholars have cited many times over (I've seen in the literature, I've been in it).
Then, look for this book on Inspiration and Innerancy (or google something similar, but by scholars, not some amateur with no credentials):
Defining Inerrancy: Affirming a Defensible Faith for a New Generation
I will be writing on biblical cosmology and Inspiration and Innerancy on my blog in the coming months : mtl-ct.ca
For now, my latest post is about Peer review, its importance and its flaws...
