I've been thinking about something recently. Dragons show up in the mythology of several different cultures (Norse, Chinese, English, etc.) dating back several hundreds of years ago. Some of these cultures being so immensely different and separated but still coming up with the same creature seems like a huge coincidence, so the question is... Is it possible that dragons did exist some time long ago (perhaps before we had any system of writing or maybe even during the time of the dinosaurs)? What do you guys think? Please comment and share your thoughts.
