Factual error: Although "Myearth" is a fictional site for the movie, all satellite sites (such as Google earth, etc.) show images during daylight hours (though I've seen rare exceptions of images during twilight hours). How could Buddy expect to not see his house (with or without lights) when the images show during the day?
Factual error: At the end when they show the lights shining in space from the satellite it is shining from the center of the map. The entire time they said it was set in Massachusetts, which would mean that it should shine from the right side of the United States coast.
