Which is strange because if they are made up don’t you think people would claim they heroically shot at them?
I think there are probably a lot of people faking videos these days; and they faked photos in the past. But I don’t think all these people in past decades were hoaxing their stories - in a lot of cases all that disclosing their experiences got them was ridicule; and for some, lives and careers were all but destroyed. This happened particularly with some of the police officers who saw things.
I don’t think there is any doubt that people have seen and experienced unexplainable things; the question is ‘What?’.
