ok well once you don't believe in video evidence or photographic evidence then there is no evidence that could convince you of something other than actually experiencing it yourself. In which case people will just believe what they want to believe.

Usually there are other witnesses, other video sources. The more material exists, the harder it is to make the fake believable. You have to consider the sources. Who published the video, what are their motivations, who pays them.

Really, that's "internet user 101", I can't believe we're having such a discussion on HN :)
