so I was out to dinner with my family last night, and my stepdad and my sister were talking about this show they saw on the history channel that they had both seen. And they said it outlines a UFO sighting where the entire city basically (near Pittsburgh they think) sees a UFO that's over a mile long. But they said there were hundreds of witnesses, with some extremely credible sources involved. Has anyone ever seen it? And if so, do you know the name of the show? I'd like to see it.

I believe you may be thinking of the
Phoenix Lights.
May I suggest, while UFOs and the paranormal seem sexy, get yourself a grounding in science first before going down this road. A healthy dose of skepticism and critical-thinking will help you a great deal along the way, not just in the study of the paranormal, but in your day-to-day life.
A Demon-Haunted World by Carl Sagan is a great place to start.
