QUESTION: My little girls have learned about dinosaurs and they asked me how come the bible doesn't talk about them. I don't know how to answer this question.
ANSWER: The Bible is not meant as a history book. While some portions of the Bible, such as the Gospels and the Acts of the Apostles, are factual and historical, many other parts of the Bible are not meant to be historical. The creation narrative in Genesis, for example, is not meant to be a historical account of how creation actually took place. Rather, it is meant to convey the lesson that God is the creator of the world.
You can explain to your little girls therefore, that the bible is not a "history book". Not everything that happened in the history of the world - such as the existence of dinosaurs - "have" to be present in the Bible.
History and science books will tell us about dinosaurs. The Bible, on the other hand, tells us about the story of God and our salvation history.
