Dennis Kucinich just got a little lonelier in his position on UFOs. During the debate this week, Kucinich cited Jimmy Carter's well-known experience as another example of people seeing strange things in the sky.

But now Carter has told CNN that he does not at all believe the object he and about 25 other people saw — a round object that changed colors — was actually any sort of alien spaceship.

"It was unidentified as far as we were concerned, but I think it's impossible in my opinion, some people disagree, to have space people from other planets or other stars to come to us," said Carter. "I don't think that's possible."
