There are different opinions on the answer to this question. Some people believe they once existed, but most feel they are works of fantasy. Discovery Channel made a documentary style movie called Dragon's World: A Fantasy Made Real. This movie actually caused confusion in some people who thought this was a real documentary presented by Discovery with actual facts. However, this docudrama was made for entertainment purposes only. The scientists were played by actors. It was advertised as an "alternate history".
There has never been a confirmed case of a dragon remains being found. There have been claims, but they have been found as incorrect or fabricated thus far. There are still other ancient reptilian skeletons that have yet to be identified. Many dragon lovers still hold out hopes that these could be them.
Some people feel that the fact that dragons are known in the history of almost every area of the world in much more than a coincidence. There are Asian versions of dragons, which are wise and benevolent creatures. According to some European folklore, dragons were eating maidens and then being slayed by knights in retribution. There were American Indian tribes who had stories of fire breathing reptiles burning fields and flying away with buffalo. Dragons are depicted in ancient art from all over the world. Many of these societies had no contact with each other.
There are some that say there have been many fantastical creatures in this world. Some of these people believe that dragons, unicorns, and other creatures are highly intelligent and sensitive beings who are in hiding from humans and may come back some day. There are others that say there is no definite proof because they do not, and never have, existed.
Dragons have filled stories from the times of King Arthur and Saint George to modern times. They are in popular culture. Some best sellers of our time, Eragon and Harry Potter, are full of dragons.
One Opinion:
Yes, dragons are scientifically plausible.
They may just not have been discovered.
Another Opinion:
From the looks of them, dragons look like they will not evolve on their own, but rather need to be artificial life forms. In other words, they are possible biologically, but no one has seen one yet.
Another Opinion:
Dragons cannot exist, for how they are written about is impossible. BUT, there is a dragon called a Komodo Dragon, it's just not the kind of dragon you're thinking of.
There are no fire-breathing dragons where humans have explored, so if such a creature does exist it does so outside of the known boundaries of space. The biologically improbable part is the fire-breathing bit: it would take significant adaptations to develop the ability to collect, store, maintain and then spew flammable materials (many of which are extremely caustic to living tissues). Also, there is currently no plausible method by which an animal would be able to light this material on fire as it spewed it back out of its oral cavity.
However, there are some living creatures given the name dragon (although they often don't look much like the pictures in fantasy books). These include the Komodo dragon (a large terrestrial lizard on South Pacific islands with incredibly toxic oral bacteria) and the leafy seadragon (a fish native to the water of western Australia).
No way. Just a myth. Dragons have a little chance of existing, but fire-breathing ones aren't real at all.

yes and all dragons exist no matter what you say I will always believe in them :)
Dinosaurs existed. We're not too sure if dragons did. In other words, Dragons exist in the "mind" Dinosaurs exist in the museums. Dragons also exist in literature and in scuplture. Not all dinosaurs are extinct.

No. Dragons are mythical creatures. They only exist in books, movies, and people's imaginations.

No, and witches do not truly exist(nor do dragons).
