You’re right that we don’t specifically talk about dinosaurs in that book, but here’s our take on it. There is no question that dinosaurs existed. The question is how they fit into the biblical story of creation. Young-earth creationists usually argue that the big amphibious creatures (the Bible term “leviathan” may describe these animals) were created on Day Five, and the dinosaurs themselves were created on Day Six–the same day as Adam and Eve.
