I've never seen any valid evidence of valid Marian apparitions being part of UFO phenomenon. I've never made a critical study of fraudulent Marian apparitions to see if there was anything to them that might qualify as such.

The UFOlogists who obsess over these things will "see" evidence of such anywhere their anti-Catholic bias takes them, so I refuse to accept any of their claims at face value. They have an agenda that is not holy, and many of them are already deeply immersed in the occult themselves, whether they know it or not.

What proof, from scripture (my only valid standard), is there that Marian apparitions are valid. I do realize RCC tradition says they are, and some Pentecostals say they are not. I am not Catholic or Pentecostal.
