"Interesting belief. "

" The theory of evolution of dinosaurs is all very good and what not, BUT they really don't have much proof about it. There fore it stands to reason that either birds apoped aout of no-were, or for some reason fossils of this evolution ar lacking, or birds evolved from other creatures and randomly their body and constituion remarkably resembles that of dinosaurs and other big reptiles. The first theory is basically impossible if we follow the rules of evolution and other such theories, and the third is so unlikely its virtually Zero.
Thus it IS possible that the reason for the lack of fossils be dragons. To most people the idea of anything living larger than a horse is huge, gargantuan, gigantic, etc. added to that the idea of any reptilian that has being constantly portraited as a "fary tail" and able to destroy humans, and cattle so easyly, it is easy to see why most would believe a dragon a "myth" and "impossible".
If truth be told dragons are very possible, and very real. Infact science used to (they changed that after extensive research and opening their minds to possible theories and ideas that before they considered "void of any intelectual knowledge" and "pure fantasy") say that bee's should not be able to fly. But as everyone knows they can, if we were ruled by science bee's might not exist.
So the same can be said for dragons. "
