The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The truths about God, life, and people that those stories (Genesis 1-3) trying to convey were the power of the almighty God that created everything, including life on planet Earth, including humans. And on the 7th day, he rested. Then, Genesis explains the human's sin and how men and women were banished from the Garden of Eden or Paradise.
What were the main points of the stories in those chapters?
The main point of chapter 1 is the story of how God created the heavens, planest, the Earth, and everything that exists. The main point of chapter 2 is how God created man first, and then, from a man's rib, God created a woman. The main point of chapter 3 is how God banished man and woman for the sin they committed in the Garden of Eden.
Of course, the stories reflected on the Bible -in this case, the Old Testament- are metaphors aimed for the reader to have a better comprehension of the symbolistic idea of the beginning or the creation story.
