It's very interesting, isn't it. I saw ball lightning one midnight in about 1983. There is no doubt about what I saw, stone-cold sober as I went outside to get the cat in There is was, floating for three minutes low over my street's rooftops, heading for Epping Forest, a fizzing, incandescent red globe as big as a beach ball. As far as I'm concerned, ball lightning is true. But I'm not asking anyone to believe that. No-one else was out and about, unfortunately. I don't even mind being called deluded. I saw what I saw and you can't change my mind. I've researched it thoroughly (and honestly) ever since and nothing I've found out has worked against what I saw. I could set up a ball-lightning religion. People have set up religions on far shakier foundations, so why not? All I need to do is work out a way of persuading people that ball lightning will get you in the end if you ever dare say it isn't true. I'm working on it. I am the ball lightning Messiah!
