No wonder you were at a loss…that’s just rediculous.
UFOs are demonic appearances, which demons do to create fear. I’m guessing that the spinning sun is what this man is talking about. I had actually heard an exorcist priest say they are demonic beings. Some believe them to be cherubim demons, i.e. wheel-like in appearance.
Our Lady at Fatima was not a trick of the devil. How does he explain the appearance of the angel handing out Holy Communion to the children? The devil would not recommend someone to say many rosaries, as she did to Francesco. He also would not be pleased about someone who went to heaven.
Of course, he can believe what he wants, because these apparitions are not required beliefs of Catholics.
