Science textbooks are full of all the basic ideas, formulas, and information needed to move on into any field of scientific study or profession. There is no way to advance in your education and become a doctor or researcher without understanding the basics. How would we feel if we enrolled in nursing school or an advanced class without having read the foundational books first? When it comes to stories (including the Bible), the same holds. What comes in the beginning is necessary to understand anything that happens later. We must understand the Pentateuch in order to advance in our study of the Bible.
