I'd like to believe there was. Partly because we can't be alone. I'm pretty certain theres aliens, ghosts, a whole host of supernatural, things out there, and I believe in evolution. So with my own theories I do think that they could be there. The same way we did, instead of chimpanzees and all that, couldn't bats and other animals have evovled to such heights that they are human? But a different type of human?
I think it could happen.
I'm not sure about the legends have to come from somewhere, because vampires could have came from cannibals. For example, Dracula spawned from Vlad the Impalor, a Romanian Prince that drank blood and murdered countless ammounts of victims, placing their heads on spikes all the way up to his castle to ward off intruders. Vampires could have just been folklore.
No one could ever really know, unless they are a vampire, because even if you met someone who says they are, how can you be sure their not some kind of derranged lunatic? The world is a strange place, after all.
