Various Bible authors, and even Jesus refer to Genesis as true history. I also accept Genesis as true history
No they didn't, they appealed to the purpose of those stories which is to explain the fallen nature of man and his adversary. King David seems to not have a literal interpretation of the Flood, which means that the common Jewish idea wasn't literal either. In fact, many cultures examine the same story and come to a like conclusion- it simply wasn't an apocalyptic event.
What you fail to realize is that everything from Eden to the Ark is straight up Jewish oral tradition eventually recorded by Moses' successors. Y'all act like the Bible miraculously fell from the sky one day.
In reality, these stories are heavily codified and symbolic. The Serpent, fallen from Heaven and crawling the Earth, Eve made from Adam's rib, The Tree of Knowledge, The Tree of Life- even the precious stones in the rivers- all these things have symbolic meaning to them.
Jesus on the Cross is the Tree of Life, Satan is adorned with those stones in the river in Ezekiel, The Tree of Knowledge is of the world..
I mean, how do you just deny these things and continue on blindly with an arbitrary presumption
