You are quoting from a book written by people who understood the world about as well (and maybe not even as well) as the people living at the time it was written. A book that believes all people descend from Adam and Eve, and from Noah and his three sons, despite the fact that other origins stories exist when if Adam and Eve existed there would be no other origin stories.
A book that claims that God chose a tiny group of people to give his word to, despite all of the people descending from Noah, rather than give it to the entire world.
