I have edited my post from Sept 2018 a little.
The Bible is not a science book. Science asks the question “How?” as in “How does something work?” and there could be test done to try a theory. Theology asks “Who?” as in “Who is God?” and there for a relationship. The Genesis creation stories are written using the knowledge and words that were around some 700 years before Christ.
God doesn’t have a clock as He is outside of time and space. Did God create everything and then leave it or does He still create? I know that God will continue to create me, until I have taken my last breath, if I let Him. If I am not, then I am sinning and want to be in control and create myself.
The oldest written accounts of creation in the Bible are in the Psalms. Look into Psalms 8, 19, 93, 104 and 148.
The 7 day creation story is poetry and should be read as such. Praising God for the creation using scientific language is like a man saying to a woman that he “has chemical reactions in his brain" when he sees her. No sane woman would marry that man if he was to propose using those words. She wants to hear that he loves her and will give his life for her and future children!
It might help to bring in the Hebrew language here. Ha’adam means the one who comes from dust/soil/earth so the “dustling” or “earthling”. It comes from the word ha’adama which means dust/soil/earth. “Ha’adam”, doesn’t become “Adam” “man” until Eve is created before that ha’adam is written. Adam becomes man in relationship with Eve. Eve (Heb ishá) means “mother of all living”, “life”. “Ish” is another Hebrew word for “man”. So the story is about “the man and the mother of all living and their relationship with God, the Creator”.
The relationships between human and human, and human and God are what is important in Scripture. One second the human being is praising God and the next accusing Him for something. This is typical in the story of Adam and Eve. Adam praising God for giving him Eve and then the next moment blaming God for giving him Eve.
