>>17895233>Everybody has it because dragons are fucking cool.This is a factor. All it takes is one good dragon story, reality-based or not, and people will spread it around. With improvements as desired - the hero killed the dragon back in mythological times and that's why nobody sees them NOW; it's got extra heads; it breathes fire and lightning and disintegration beams and acid, it was created by Man's hubris, some ancient divine slut, or undersea nuclear testing; it can fly or teleport or travel through time; it changes shape when it wants to.
>>17895236Yep. Also *many-headed* entities can be derived from misinterpretations of sea anemone and cephalopod anatomy scaled up.
>>17895237That doesn't make any sense. Jews are human; anyone obsessed with them enough to cast them as the villains in a myth is going to give them a humanoid form.
