Where do dinosaurs come into play in Evolution?

Wow, you really need to pay more attention in science cl. The big bang (which was not an explosion) occurred 13.7 billion years ago. The Earth is only 4.5 billion years old. Life on Earth is only 3.5 billion years old. That's a 10,200,000,000 year difference. Also, your idea of evolution is what - a joke I'm hoping? No one could be THAT ignorant, right? Yes, that's very silly. And has no basis in reality. Dinosaurs were simply one more step in the evolutionary cycle.
