I'm not 'believing' Fox. I'm actually arguing AGAISNT assumption, RIJ. You are assuming a huge amount of what would and would not be in the story, when we actually have very few details confirmed. And yes, covering things up could easily lead to not anyone knowing. I put it to you, again, how much do you know about the real events which gave 'Mothman' its brief fame? Next to nothing, I'll bet, but that involved some extremely weird stuff (including creatures flying after ambulences and the like; none of which made it into the recent film), but virtually nobody in the general public knows about these events, because they can't be bothered to read up on them. Add several hundred years to what is going to, inevitably, going ot be a very low number of survivors and it's easy to see how virtually nobody will have a clue about these creatures. And that's assuming the Predators don't just go and sterilise the entire place, which is probably going to be what takes place.
