I can't prove there is microfilm, I guess you can't either. So you are supporting evidence that does not exist?
Poor Peter, you really do get yourself so tied up in knots, don't you, so very easily confused. LOL You're not meant to prove the microfilm exists,
you were the one who claimed it
didn't exist, remember? You were asked to back up that claim but you can't do that, can you? Fact is, you don't even have a clue where or how to start.
Peter, do yourself a favour, have a sit down, gather up your thoughts and try to remember exactly what it is you're attempting to do here because at the moment, all your doing is making yourself look very silly. OK, '
smart guy' hope that helps.
