Life After People was filmed by aliensAt times there are small camera effects that appear that someone (or something) is filming the show as if it were an actual live taping. And since the series at nauseum constantly insists that no humans survived the only logical conclusion is the entire show is filmed and produced by aliens who arrived shortly after The End perhaps to originally make a standard documentary about Humans. However after reaching the planet they discovered Humanity died out years ago from unknown causes and just decided to film the remains. A couple of months later they give the footage to Network execs who give it the greenlight and it becomes one of the most successful series on "their" version of the History Channel.
