Recently I was asked:
"What happened to the dinosaurs?"
"What are the different views from the Bible and Secular about dinosaurs?"
"Where did dinosaurs came from?"
"What do they look like?"
"When did they live?"
"Does the Bible mention dinosaurs? What about other ancient records?"
"Why don't we see dinosaurs today?"
etc...etc
