[citation][nom]sacre[/nom]Life itself is a very selfish "Force". All life wants is more, is something in return. Life thrives on receiving, everything we do is for ourselves. We give money to a friend expecting a thanks, credit, and if you dont receive it you get upset. You try and get that job so you get paid, if you dont get paid you get upset. You turn on the TV to be entertained, if you're not entertained, you get upset.So with this said, If an alien species came to earth, this automatically tells us they're far more advanced then we are because they're able to travel and sustain their species through long travels in space. So, this means we have nothing they'll want when it comes to intelligence, so what else would they want? Well, our resources. But then, if you think about it, the basic resources like water, fuel, etc is all over the galaxy, in every solar system, there are many different types of resources. So, this being the case why would an advanced alien species purposely destroy our planet, the species on it for a bit of resource they can get from Europa, Jupiter, the moon, mars etc? I personally don't think an Alien species will take the resources off our planet, specially at their level of intelligence. The only thing I can see them doing is using us for experimentation or as something else. Not as slaves, because again, at their level of intelligence one would expect them to already mastered AI, robotics can do work much more efficiently and quickly as us.So, again, with all this said... would they even bother with us? We have nothing to offer them at all.[/citation]
actually this has more to do with eco systems earths ecosystem is gnerally based off a "food chain mode" meaning something is always stepping on somthing else to get on the top. kill or be killed not not all of earth's eco system is this way thier are the rare symbiotic organisms that rely on each other to survive and both life forms give the other something in return (such as whales and sucker fish). now it is totally theorectically possible that an alien eco system is reversed in this where most the eco system is sybiotic ( like the creatures on the avatar movie) and the "food chain" animals are the rarity. but it is also likely that there is an alien eco system that is even more agressive than ours as well . both are possibilities.. hawking's beleive is merely based on the eco system we know. it doesn';t reallky even mean that our eco system is predominant kind of eco system in the univers , what if we are really the odd ones out ??? nut then again what if our eco system is tame comapred to teh rest of teh galaxy .. it's all theoretical. i sya let teh contact geeks continue on , more than likely any race that is advanced as far as we have will not get here any time soon and more advanced races are likely not with in 60 light years of us any way since man has had radio communication for about that long , it's safe to say so far any thing that has picked up signals from earth would have already been here had they picked those signals up. and this is ofcoruse assumign that any alien life form with in 50 light years of us is advanced enough to pick up that weak of a radio signal in the first place.
