i always find it intresting how everyone assumes any alien visitors would be part of an alien races goverment and they would act all proper like~?Seeing as sightings have been occuring for at least 50 years or so, if aliens wanted to annihilate us they would have done so already so I believe hawking is incorrect, they are as interested in us as we are in animals in a zoo.
Maybe they want to help us and give us some of their tech in exchange for our tasty big macs.
maybe they are "climbing in our windows snatching our people up" and putting us in a zoo
