You do realize that the purpose of these accounts was to pass down knowledge, right?
Haha. You got this from the tree of knowledge? Where are your sources? You can't just assume what you are reading is allegorical. How could ancient peoples believe in a big bang when they knew nothing about it? You base things on present knowledge and that people in the past were misled or were wrong. They had to decide whether to believe the Adam and Eve story, as well.
Here is what you should have gotten from Genesis.
1. God created existence
2. Everything he created is good
3. What he created was done in steps
4. Man is a product of that creation
5. Man is unlike any other creature in creation
6. Man is made in God’s image in that he is a being which knows and creates
7. Man was told to go forth and be fruitful
8. Man was told to do as the original creator; to create for 6 days and then rest
9. Man knows right from wrong
10. Rather than abandoning the concept of right and wrong when man does wrong, he rationalizes he didn’t do wrong
11. Successful behaviors naturally lead to success
12. Failed behaviors naturally lead to failure
13. Pass it down to the next generation
