Every civilization on every continent believed in dragons at one point or another, not as a source of mythology, but in a "We don't go up that mountain, dragons live there" sort of belief. But we have to go with what we know, what is most likely. Is it possible that fire breathing, village destroying reptiles existed? Or did people find dinosaur fossils and extrapolate from that fantastic creatures? There is a great series of documentaries about that btw. Anyway the point is that the fact that it is widely accepted doesn't mean that it is more credible. The gospels are easy to dismiss man, none of it was written while Jesus was alive. And if you look at 1st and 2nd century christians, you will find that there was no uniform doctrine, some christians didn't believe Jesus was a real person around the time the gospels were being written. How could something be true when people whose parents and grandparents were alive when he was raising the dead?
"In our youth, we lacked the maturity, the decency to create gods better than ourselves so that we might have something to aspire to. Instead we are left with a host of deities who were violent, narcissistic, vengeful bullies who reflected our own values. Our gods could have been anything we could imagine, and all we were capable of manifesting were gods who shared the worst of our natures."-Me
"Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all of which may be guides to an outward moral virtue, even if religion vanished; but religious superstition dismounts all these and erects an absolute monarchy in the minds of men." – Francis Bacon
