Either you have seen a UFO or you have not.
Once you have, well, you tend to believe in them...
Two groups of friends miles apart saw the same object in the sky here in MA back in the late 80’s. One group was catfishing by the river that night.
I heard the story from one group then a few days later heard the exact same story from the other group. They ended up getting together and talked about it. They agree that they both saw the same object. The said it wasn’t a plane, helicopter, balloon, swamp gas etc. It was a defined object that moved in ways no man made machine could ever do.
All of them (4 guys) are now absolutely convinced that UFO’s exsist.
