I believe people see things they don't understand. I do not believe in life on other planets.
There were quite a few UFO sightings in the town I came from. My sister told me that her friend was sending things out every few weeks. I can't remember exactly what was involved, but I do remember a couple of the things he used were candles and I think plastic bags. I saw them a couple times, and they definitely looked eerie. The TV news ran a story about UFOs in Vista, saying that people had reported seeing them. I wrote to the TV station that reported it, to let them know what they actually were. Of course they did not report what they were.
