Story:
A terraforming robots attack the Earth. The U.P. (united planets) sends help to save a human species from destruction (and all other animals). The robots were created back in days before U.P. existed and when planets didnt like each other very much. Since they created those war machines that went out of control, they send a race of Keerg (greek) to save humans.
Only 2% of all human (and species from earth population) survives.
They are send to a new planet, created just for them. However for humans it fells like a prison. They made a deal with illegal immigrant traders to send them over to other planets to find a new life. The Keerg race doesnt have founds to support all human population in camps, so they made a deal with traders to get them to other race planets (wich by a space law, they should take the refuges).
Other planet nations start taking in the humans. However since humans can work as a cheap labor, and since their planet doesnt exist any more, they cant be deported. Soon humans try to force their culture on aliens. One of the humans who didnt get a free home, eat a Bzthgz (causes humans to go boom) as a protest.
Some of the planet nations want to get out of the U.P. . ....and so on and on.
Yeh it would make a intersting movie. But the question is...if you were a alien, would you support humans or would you want them dead and out of your planet?
What if your alien sister would marry a human? ..and so on...
