I've seen 1 or 2 documentaries speculating about alien life forms and wonder why they'd be substantially different from life here. Given the narrow parameters for life, evolution should produce similar life forms wherever life exists. |
The parameters are only narrow when the definition of life is narrow. Such logic becomes almost circular, "Life can only exist in the conditions that life such ourselves exists in, therefore all life must be like ourselves." The premise that all life would require conditions like those required by known earth life has not been demonstrated theoretically or empirically.
Our ignorance is so bad that we can not yet even rule out life evolving in the exotic interior of a neutron star (albiet exceedingly alien and bizarre life).
What's more when it comes to intelligent life natural selection might well be routinely short circuited culturally leading to an endpoint quite different from the sort of life we observe as a result of natural selection. Such intelligent 'life' could end up looking something like the super intelligence in smac transcendance or even a bunch of oragnisms plugged into perfect drug type machine that keep them perpetually content and happy or even bodies engineered to only be pertually content and happy with an ancient artifically intelligent infrastructure to maintain their bliss. Who knows!
Bottom line, it's probably a mistake to extrapolate from earth life to the characteristics of alien organisms much less to the behavior of alien civilizations. My guess is that if hostile technologically sophisticated aliens were the rule or even remotely common we wouldn't exist as any civ that lasted longer than a few hundred thousand years could have long since expanded through the entire galaxy millions of years ago and exterminated all potential rivals in their cribs so to speak. They wouldn't even need to discover a way to travel faster than light to finish the job in such a time frame.

How can any life or any thing exist at all? Obviously it does, but how can it? I know it's an impossible question with the information we have, but maybe it's the one the inevitable galaxy spanning aliens are working on instead of hunting down all the sub species in the universe.

The only way we'll ever find out is if either we or they develop technology so advanced that "paradise" would be within easy grasp of whichever one is able to make the trip to visit the other.
