ALIENS?????
Wouldn’t they be referred to as ‘Undocumented Space Travelers’?
Like Sienfeld opined....
A space craft hovering above you while you are walking your dog.
Dog stops to ‘do doo doo’ and you stop and pick it up.
Don’t really have to wonder ‘who is in charge’ now do you?
Kind of like Hitchhikers guide, where the visiting alien thought the predominant life form were cars.
