Did dragons really exist?
No, there is no scientific evidence that dragons ever existed — but absence of evidence is not evidence of absence, and remember also that it’s far from decided what triggered the first concept of “dragon,” which exists in many cultures, settings, and mythologies. The program you describe is probably “Dragons: A Fantasy Made Real”, which was a mockumentary based on a “what if dragons were real?” premise. Maybe someday something will turn up, but for now, the dragon shares space with unicorns and mermaids in the scrapbooks of cryptozoologists, not the real world. Sources: http://en.wikipedia.
