Aliens living, travelling, and existing without human destructive traits are about to be infiltrated by human sperm sent out into space by NASA!
Special, crew-less space vehicles, loaded with the stuff, will be launched in the hope that passing UFO's will lock onto them. Aliens can then board the ships, read the instructions about artificial insemination, written in a handy guidebook, and start to multiply with human sperm!
Nutty, human scientists, believe that humans mixed with aliens, can produce a race of pristine beings, who can then return to earth and turn it into a peace-loving, Utopian planet (Dream on!).
Anthropologists are quite concerned about sending human sperm into space because there's enough junk floating around the planet up there, and having half-aliens mixed with half-humans could create even more junk in space! After studying the human race with all of its faults, anthropologists are strictly against contaminating alien beings with our sicknesses, because up till now, no alien being has attempted to destroy our planet, except Trump, Putin, Hitler, who are (or were) certainly not normal human beings!
NASA is determined to continue the experiment, and hopes in the next 20 years a new race will descend upon the planet to save us all from an apocalyptic disaster!
Trump has not tweeted on the experiment as he believes his sperm is so pristine nothing or nobody can be better. However, he has booked a VIP ticket on a space ship when the shit hits the fan, which he has caused!
And only God can save the aliens when he gets among them!
