Op doesn't describe me and my beliefs but instead builds a strawman and tears it down. Different atheists have different ideas on different things. They aren't a monolith
The only unifying thing required to be an atheist is to find god propositions unconvincing. Anything beyond that and whether or not the atheist is gnostic or agnostic is tertiary
When I look at Religious books like the Bible, I look at them like I would with science data. I use that book as the data base for my analysis, and try to keep my reasoning within that range of data. I am not judging the data, but rather approaching it like I would if a was analyzing a book from literature.
One can still analyze content and find hidden message even if fictional books fro Shakespeare or the TV shows like Star Trek, since they often contain timeless messages, even if the characters are fictional or not. One can still use the power of reason to analyze any data set; comic books, and gain experience developing critical thinking skills based on the possibilities that the data set allows. Denying certain practice data sets, prevents any exercise of the mind; fat head, leading to name calling; emotional thinking instead of reason.
If you ever took a literature course in High School or College, you often had to read and analyze a work of classic literature. I always thought it interesting, that many aspects of the human condition, are the same today as when the a book was written; War and Peace. However, I also could see how people were different, due to their times and their lack of seeing into their own future. Religious books teach us timeless human wisdom as well as allows us to live in a different time, so we can analyze and infer how we would have behaved, back then, if you did not have the benefit of 20/20 hindsight.
If the topic is Noah's Ark, this is the data set. I will reason with that data based using my development skills for reverse engineering, to help me fill in and set the stage. This is called Creationism, by the Atheists, but I call it reverse engineering based on the sparse fossil evidence. I will help to fill in the missing links based on that limited data set. It often takes ingenuity.
Based on all the data, my best integrated analysis is Genesis is speaking about the evolution of modern human consciousness, through the eyes of people living at that time of change. It was a time, when the unconscious mind was much closer to the surface and the wall between realty vision and unconscious projection overlay, was very low.
The ego secondary was leaving the womb of its unconscious development, and becoming more differential. Religious works are like the IT of consciousness, since the data best fits one aspect of science; forensic psychology. They were closer to the operating system of the human brain, and mapped it out; software code has it own language that can different from hardware.
