Do you really beleive that aliens visit earth from time to time???

I think that UFO visited earth for sure, because I have a direct testimony of some UFO sighting in 1978. I was born in 1978 so I can't tell about what my parents and brother and sister have seen. I am talking about circular coloured lights, red and blu. They weren't helycopters or airplanes...because they didn't moved in a linear way, but in a strange way. They were really fast. The side phaenomena was that TV (one of first colour television) always displayed garbage on the screen when there were that strange lights in the sky. They came many times...always with that flying saucer with many lights running on them. And everytime TV was disturbed. From that time, no other UFO sight from here. I am from south Italy! I'm really interested in UFO and paranormal! Talk to me of your experience, people!

Since I have never met one face to face, I'll say no until I do meet one.
