Do you believe in UFO?

[spoonlamp]

Define "UFO".  Do you mean any object in the sky that cannot be identified?  Terrestrial or Extra-Terrestrial?

A good place to start. Many people report seeing UFOs, but that doesn't require belief. How about if you see a UFO and call it a UFO for 15 minutes of watching it until you realise it's one of those floating balloon fire candle things - it WAS unidentified but now it isn't!

If you mean do I believe in visitations from other worlds then no, I don't. I think you'd be mad to think we're all alone in the universe (especially with so many planets being discovered all the time) but to go to all the trouble and expend all the energy required to make the trip here I think any visitor would have made more of an effort to introduce themselves...rather than mutilate cattle and kidnap rednecks...
