Since dinosaurs were first given a name ("terrible lizards") in 1841, they have fascinated people. Our testable creation model says God created dinosaurs to roam the Earth roughly 230 million years ago, and many different types of these creatures dominated the landscape. Their time on Earth ended when a 6 mile-wide asteroid impacted Earth 65 million years ago. Some Christians say the Leviathan and Behemoth mentioned in Job refer to dinosaurs, but we disagree. Because humanity arrived on Earth much later, no biblical author would have had contact with dinosaurs. The most popular scientific model claims dinosaurs evolved into birds, but we reject this view also. Instead we argue that both birds and dinosaurs were specially created by God to fill the livable environments available on Earth during their respective eras.
