Yeah that's fair enough and i guess that's about where I stand on UFOs. As I mentioned earlier - you'll never know for sure if their real unless you see one yourself. Even then, it would have to be a pretty definitive sighting ( like close enough to see your reflection on the hull

)
I fully agree with Ian Robinson's list below, and I can see a vast majority of reports fitting into one or more of those catagories.
But with the sheer number of reports (they go back several hundred years - recorded anyway) I find it hard to go past the
possibility that perhaps a few of them may have been the real deal.
