Did We Get A Visit From Aliens Last Night?

Been seeing this all over face book today and hearing lots of poeple talk about seeing the same thing!  A "green light" in the sky...From Suzette Jones-Arnold on facebook

Ok so I was driving towards the house on 15th at dark . I just pulled away from being stopped at the light . what looked like a plane's light passed in front of me in the sky . I noticed it was going in an arch and was about to stop the car cuz that threw me and then I though . Well if that's a plane it's crashing . Then I thought it must be a falling star or a comet and the light coming off of it was green . WOW!!

I read a few of the comments on her status and it really seems like this was a UFO!  People talking about this "green light" flying through the sky, making sharp turns like no plane can do!  FREAKY!  Did you see this?  What about UFO's in general?  Gotta story you wanna share with me?
