This subject calls out all sorts of fuzzy thinking. It seems to some who do not seriously consider the information available and its credible sources, or who has not had clear and carefully considered 7 personal encounters, as I have. Whatever your opinions, keep them subject to an open mind to avoid ossification of your thinking machinery.
Seven you say? Yes, over 86 years. I just carefully look at the sky’s, not looking or hopping for anything strange. At my age, I’ve had plenty of shy watching, and never tire of it.
