Hawkings take on any motivations of aliens has nothing to do with his area of expertise. He's no better equiped to determine their motivations than any of us. Thats like Oprah commenting on astro physics. Earth is the Alabama of the Universe, if they were tuned into any of the town hall meetings they're not coming down here among ...US.
Another option on the poll should be : Aliens cant be bothered. I mean if alien civ is advanced, perhaps they see us like we see an ant crawling across our table, eminently ignorable and insignificant

Hell, we have to defend ourselves from the aliens right? Ah, a new cold war without even an actualized enemy. They've even gotten to StepheHawking ....but how? Grants? Threats? :eek:
