Because the first 11 chapters of the Bible were never intended to be read literally.
Where do you get that idea?
No one said bad promotes good.
Then we agree on this point.
Good coming from bad is logical.
Now you need to explain what you mean by "coming from".
History, experience and the OT show that when a people become successful they become proud.
Some become proud but not necessarily everyone. I don't think the success forces them to be proud. They choose to be so.
Then they forget the things that made them successful (i.e. they forget God) and they fall.
Some may forget God but not everyone. I don't think the success forces them to forget God. They choose to not be grateful to God.
But from this fall (i.e. suffering) they remember the things that made them successful (i.e. God) and they change their ways (i.e. repent) and return to the things that made them successful (i.e. remember God) and then they succeed.
I don't think the suffering forces them to think of God. It does bring them to less desirable state and their dissatisfaction may cause them to think over why it happened and they may remember how God blessed them and repent and seek to return to him Not all, given these circumstances, will return to God.
Because of our imperfection and the fact that we cannot become perfect without free will, God places us in this temporary existence of good and evil so as to learn to praise the good and detest the evil. However, not all of us make that choice. Some tend to relish the evil and despise the good. It really comes down to how we, with our imperfect intelligence, process the information of good vs evil and which master we list to obey.
It's biblical, logical and what happens with some frequency at the nation and individual levels.
I agree that good and evil exist and that the experiences we have give us a choice of what we would rather follow. But to say that good comes from bad makes it sound as if you are saying that bad is essential in order to become good. I see evil as the opposite of good and can give us dissatisfaction to where we might choose good over it. However, some tend to love the evil over the good and hold to it. In such cases good does not result from bad. Good and bad give us choices that we can make but do not force the change. Some can hold to good or evil depending on their thoughts and desires without it causing a change and thus saying that good comes from bad is not always true. Conceptually, I don't believe that good or bad can exist without each other. You cannot have good without bad and you cannot have bad without good. Conceptually you cannot create one without creating the other. However, I don't believe with our free will choice, that we must do bad to choose good. I think your understanding is definitely with merit in that we can choose to regret evil after experiencing it and we can choose to become prideful after experiencing good. The feelings of regret and pride can motivate us to make different choices in our lives but they do not force us to do so. If we were to compare this to being created to have a perfect intelligence from the beginning, we would always make the right choices and never make bad ones. As imperfect intelligences, we have to grow and come to know what the best choices are and good and evil help us understand between these two. I don't think that one necessarily brings about the other but they can influence our free choice to help us make a decision.
