Stefan frowned for a moment before shrugging. "I presume so. Every vampire I know was made from a human. There are still some of the originals around, in my world at least, but they're definitely not the sort of person you sit down for a nice little chat about history with..." He shuddered at the thought of Klaus, mainly because of the threat he posed for Elena. Still, he felt sure he would know if vampires came from outer space. It was almost preposterous.
