Before us there were Aliens

Before us there were aliens. The human race started in a petri dish as an experiment for alien scientists. They wanted to test the living conditions of earth because their planet was too overpopulated. So they made a bacteria that would evolve incredibly fast and they plopped it on earth (along with a few other creatures like dinosaurs and cockroaches). 
Around the year 1600 on earth, the project lost funding and was bought by an alien TV network. The network took all of the footage from the experiment and uploaded it to their channel. THEN they kept filming with all of the hidden cameras on earth. Sometimes they like to throw in something to make the show more interesting--for example, when they added a bunch of greenhouse gasses to cause global warming. Everyone has their own tv show but there are also shows about schools, stores and offices. So if you go to school or your job you will be on the tv show for the place that you work at. If a show isn't popular it gets canceled and the person dies some way or another. If a show does really well but the person dies, that person is cloned and brought back as a baby to live the rest of their life in a paradise on an alien ship. This happened with Gandhi and M.L.K. Some things that humanity has achieved were real like the moon landing, but things like the J.F.K assasination were orchestrated by the aliens.
