It all makes more sense when you consider these stories in their historical social context. They’re a compiled bundle of stories from various religious traditions that were kind of grafted together to form one monotheistic state religion to help unify the country. So you find stories from both north and south Judah for example, the two creation myths in Genesis. And you see the monotheistic god referred to by more than one moniker because they were originally different gods.
If I remember my hermeneutics, the canon is that essentially, God had “blessed” early descendants of Adam and Eve, allowing their children to thrive.
It wasn’t until after the flood I believe that incest becomes more of a theme in the Bible, implying that they shouldn’t have children.
But it’s been years since I gave this any serious study so I may be remembering incorrectly.
