When Did Dinosaurs Live? In this session Mike examines two evidences for when dinosaurs lived: 1. The origin of dinosaurs. 2. The scientific evidence. Mike shows that the evolutionists really don’t have any observable evidence to support the claim dinosaurs evolved into existence 220 million years ago. In addition, evolutionists have not been able to find any transitions leading up to the dinosaurs. The fact that we are finding soft tissue, red blood cells, and proteins still in their bones is convincing evidence dinosaurs have not been dead for millions of years. Based on what the Bible teaches and the scientific evidence, the logical conclusion is that dinosaurs and people lived at the same time.
