Di’s Crackpot theories post #1: Dragons

Dragon Fountain
Let’s say St. George really did kill a dragon, not a religious or political metaphor. I’m going with the idea that the dragon really did breathe fire, and not as a byproduct of alcoholism.

My theory on this is the following:

Dinosaurs existed when the earth consisted of a different atmospheric mix; certainly most went extinct because of tripping and falling in a tar pit but a lot gradually lost the ability to breathe.

As a behavior adaptation, some of the reptiles moved back into caves since their exhalation consisted of gases that, when hitting the increased oxygen, set stuff on fire. Sure, sounds like a great defense mechanism but awkward when you prefer your small furry critters medium rare.

So St. George killing the dragon… the dragon totally let him.
