I drove past a cemetery the other day so is that not proof that Buffy exists?

I was watching Buffy one night and the next morning I drove past a cemetery. I think this is evidence that Buffy the vampire slayer exists and so do vampires coming out of their graves at night. Of course nobody knows this because Buffy works at night and only vampires come out at night. So I'm relying on faith that Buffy exists. Is that ok?
