I don't know where you get that idea. Believing that God created the universe doesn't necessitate denying that dinosaurs existed. In fact, the Bible uses language that speaks to the existence of dinosaurs. The theory of evolution, on the other hand, is simply a series of intellectual gymnastics that attempt to explain the existence of the universe minus an intelligent Creator. If you choose to live your life as though God doesn't exist, that's your business. But mocking those who believe otherwise simply shows ignorance and intolerance, and doesn't change the facts whatsoever.
