Are fire-breathing dragons real

Ummmm, if you mean ARE dragons real, then yes. I saw 2. Don't believe me if u want, but I did.

======= I suppose the Word "dragon" means different things to different people,

but the fire-breathing monsters that St. George is pictured as fighting are not real, in the sense that they exist in the physical world. They may be real to the artists that draw them and they may be a remnant in the psyche of extinct dinosaurs that may have once co-existed with men. and terrorized them.
