Since we are all humans (maybe not the Australians: they might be aliens), we are all nutty in some way. We have been throughout our history. And maybe one of these days far in our future real outer space aliens will be observing us and say to themselves" These nasty creatures called Humans are a constant annoyance." "I think they need to be exterminated." "Then we can eat them and rape their world of all it's minerals and water!"
