no you don't
you just like to believe in a romantic imagination of a creature that was created by sailors to make their meetings with whales more impressiv to the listening crowd in a pub
I'm sorry(actually... no, I'm not, but that's a good start for a sentence, isn't it?) to break your idea of our science system, which in your words doesn't allow dragons to exist and discredit anyone who finds proof
unfortunatelly science in this world only works with evidence(real evidence, not only deductions, deductions make theories, they can explain things, but not proof something)
and there has been no evidence for dragons so far
ofcourse your deduction could lead you to the conclusion that all the drunken sailors and highly imaginative people of that time were right, and today's science is blind for not seeing the obvious proof in a fake sceleton in a dubbed indian "news report"... hm... actually you could believe that... it wouldn't change my opinion about you crazy person a bit
people who spent way too much time in their lives never getting out of a classroom to evade the confrontation with the real world spent our tax money on dragons and other silly things and wrote many books about it only to come to one conclusion(I'm sure you can read them in your local library), which I, in my humble greatness, can sum up for you: people threw all the evil things(parts of a snake, fire, etc) together to impress people and to make people afraid
kinda like the misuse of religion, but religion had an intelligent man at the beginning and the bunch of idiots, with their own objectives, managed(and still manage) to produce enough slightly disabled brainwaves, with their want-to-be cunning minds, to misinterprete words to make them justify more or less every next idiotic thought someone had
so... myth creatures are the exact opposide(from the origin, the goal is still more or less the same): idiots create them and intelligent people end the line of believers
where are you standing in the line?
