1) Nobody could affirm Gen 1 as an account that could ever be affirmed by science.
2) A "natural" explanation is science's only means of explanation.
We are talking about two different frames of reference.
YEC requires Genesis 1 to be a cosmology which science certainly refutes. YEC is applying ontology to cosmology.
Yet science can only explain a cosmology, never an ontology.
In layman's terms, Science can certainly explain How. It cannot explain Why. The difference is a category state of knowledge. Genesis is speaking to the functional state of why humans, and the cosmos exist. The explanation of how that occurs is not in view in any sense. The initial cause of the "big bang" is an ontology, afterward only science can reveal the intricacies of the How of a cosmology.
The basis of faith in the Creator informs us to Why science sees what it sees. On the other hand, Science can only explain the how and have no means of determining why.
I know this is basic, but I get frustrated with the arguments here between science and the Scriptures because so many of the arguments cross the categorical lines between cosmology and ontology.
Anybody has the right to choose which ontology speaks to their faith belief. The reason for the Atheistic Evolution is that the scientists involved have chosen the atheistic ontology. We will never be able to use science to prove the ontology of Christianity.
Try reading John 3:1-21 and do a word study comparing it to Genesis 1:1-2. It is the closest thing I have seen to applying the ontology of Christianity to cosmology. Doing so shows how Yeshua was giving rationale for the existence of the cosmos with John 3:16 as the central key for Genesis 1:1-2. They are linked. I have a study on this but I don't have a website to post it to link to this forum.
What this means is I believe that Genesis 1:1-2 is the only place the scripture refers to the cosmology in any way scientific in nature. In John it speaks of the seen (earthly, material which makes up the entire "seen" cosmos. And the Unseen (immaterial, may include energy, forces, quantum physics, and or "spiritual beings and forces "of the air").
After that it is all etiology applied as an ontology.
