Hi Sea Breeze. The idea you stated of the writer of Genesis 1:1 - 2:4 having the idea of the creative days being 24 hours long (and that analysis of the Hebrew text reveals such) is one of the key concepts (one which I learned online from a Seventh-day Adventist) which caused me to abandon belief of the biblical creation account (and by extension, belief in the Bible and in Jehovah/Yahweh God), since such a view is totally at odds and irreconcilable (at least to me) with the scientific geological (including paleontological) evidence. But, I have a question for you. Since you say " virtually every Hebrew scholar in the world agrees that the language and context of the creative days in Genesis were meant to be understood as literal 24 hr. days" what do you think of what is said at https://ncse.ngo/genesis-knows-nothing-scientific-creationism ? What is said in that article (in "Creation/Evolution Journal, Volume 4, No. 2, Spring 1983" of the National Center for Science Education) is the best reconciliation I have ever read of the Bible's creation account with science (including evolutionary science). Had I read of that article 13 years ago (or earlier) I might would remained a Christian (though not a JW), but I would have been a very non-literalist type of Christian.
What do you think of what is said at https://ncse.ngo/impossible-voyage-noahs-ark ? That article overwhelmingly makes it impossible for me to believe most of the biblical details of the story about the Ark and the associated flood, though there is some evidence for a massive local flood that wiped out lush vegetation and a human population about 9,000 to 11,000 years ago, in (or very near) what later became know as Sumeria.
What do you think of the History Channel program (I saw it two days ago on regular antenna broadcast digital TV) called "Decoding The Past: Mysteries of the Garden of Eden"? I think it makes very convincing claims.
