Ancient civilizations encountered fossils and created mythical creatures to explain the origin of the bones. They came up with giants, dragons, cyclops, and other creatures.

Dragons were from dinosaurs time
Dinosaurs existed because of the fossils we found
So Dragon do exist from the evedience we have gathered over the years

Really?...i can't believe I'm responding to this. If your asking if fire breathing,flying dragons are real,or were real? I just read a fellows post about him taking psychedelic drugs and connecting with an energy that guides us.....you should hang out with him.

Komodo dragons are very real

What The "Dragon" Is Supposed Too Be Based On.

Komodo Dragons are real but I'm assuming you mean the Lord of the Rings type dragon? I'm not aware of any archaeological evidence for the existance of such a creature but who knows, we've had some weird shit on the this planet over the millenia.

If they are real I want one

Real. But thanks to evolution, they're all small now. You can thank the increase of gravity for that.

The Kamodo dragons are the closest we have come to anything like that. I am sure there could have been other species thousands of years back, who knows whats still out there that hasn't been discovered yet.

Movie dragons no. However there is a science based case for the possibilty of some now extinct creature may have given rise to dragon mythology.

@KingPeep

Complete disproof of dragons has never certifiably happened, but if you can find some evidence to prove there was at least one dragon, you'd find something incredibly interesting.

No. When early man first began finding evidence of the existence of DINOSAURS, they didn’t know what they were, so the legend of the “dragon” was born. Of course we know better now.

I think there were only dinosaurs.

I know that dinosaur bones in China were thought to be from dragons. It would not be too surprising if bones of extinct megafauna might also be ascribed to mythical creatures.

Just like god, not real. Why is this even a question?

As far as large lizard type dragons it is possible that creatures like the Komodo dragon were exaggerated. Actual non avian dinosaurs that made it to the time of man is very unlikely though. I could see how a fossil of say something like Archaeopteryx could have inspired people's imagination. If you look at ancient text, the way they looked at things where very different. As far as dragons like the stories that were ridden by humans or stole princess I would have to say no.

There is very strong evidence that the dragon legend, at least the Chinese ones are linked to the finding of dinosaur fossils. This is likely the case for European ones as well.
The only "real dragons I know of were the 20 foot Monitor lizards encounter by the first people of Australia it is theorized that they literally burnt the forests to rid themsleves of these monsters, permenantly changing the environment.
Oddly enough the First Nations of North America didn't have dragon they referred to the dinosaurs as acient creatures, eg. "the grandfathers of the buffalo".

No. I don't believe dragons were ever real, they're pure fiction. I think the closest living things to them were pterodactyls and pteranodons.

No.

No, don't believe in dragons, I read lots of fantasy though.

When I was heavily on opioids after back surgery, I saw tiny red sparkly dragons dancing at my window. They were a pure delight. Haven’t seen them since.

Myths, just like the many gods that are worshipped.

You can view dragons on Youtube. They're made in China.

Real. But not what you think. Dragons are mythical creatures created by our brains from the combination of our ancestral mammals' predators: snakes, bears/wolves, and eagles/raptors/other birds of prey - whether out of fear or out of reverence.
