Questions:

Do you think that it is possible that dragons may have existed? Why/why not?
Do you think they STILL exist? Why/why not?

Personally, I think they did exist but man kind hunted them to the point of extinction out of fear, and that they just naturally died out from lack of food. I find it a bit far fetched that so many different cultrues across the globe could have dragons in them, but yet it's all a coincidence based on legend.

Also, there was a documentary about a year ago on the Discovery channel illustrating how a dragon could have been an off shoot of the dinosaur, how they could have survived the meteor crash (or whatever you beleive whiped out the dinos) by becoming marine animal, and how they could have gradually made their way back onto land and developed wings. They even had a way for them to be able to breathe fire that was logical.

And as a note, no I'm not talking about people who have dragon souls. I mean the actual physical dragons.
