Dragons are so universal in so many cultures. It wasn't until 1841, Sir Richard Owen coined the word "dinosaur" to identify the fossils of extinct reptiles...before that they were called 'dragons'. Personally I believe humans lived when dinosaurs lived and that is why we, even as children, are drawn to dinosaur toys and such. Evidence? Accounts in 16th C journals of large lizards eating sheep. There is a fossilized footprint of a dinosaur with a child's footprint. Believe what you will.
