People got excited when they went to Mars and thought they found fossilized microbes in the soil (but didn't); we leave plaques on satellite probes like Voyager I for non-humans to read and consider the "KEO space time capsules" full of Earth junk and messages to be shot into space for some alien to find; we pay astronomers to look for signs of alien planets too distant for us to reach, but that might be inhabited by something else... and others to listen for signs of intelligent or organic signals in the cosmic background racket of the stars.
...Why?
Do we really wanna find an alien? Even if it's just a bacterium that might infect earth? Even worse, what if it's a gross tentacle thing that has no interest in reading our plaques and messages and instead would rather co-inhabit the earth, or take it over? Or maybe just slaughter us for fun like Predators or comical Martians? Or even worse be stuck with a million immigrant catfood-loving prawns?
I don't quite understand the fascination beyond fantasy of meeting aliens. What makes us think they will be friendly, or even want to meet us? What makes us think the meeting won't be harmful for both sides? I think I recall even Stephen Hawking suggesting it's not wise to encourage alien life to visit this planet, if we look at our own history of exploitation and colonization of newly-discovered lands, and the phenomena of invasive species being harmful, on Earth alone, never mind Rigel 7. We aren't advanced enough to go any further than Mars realistically, so if something came from outside the solar system, you can probably be sure if it does arrive in a big spaceship it's got the technology to shred our asses.
...do people actually REALLY not wanna be alone in the universe that bad? Are we hoping aliens will come out of the blue and solve all (mainly self-caused) social and economic problems?
What do you think? Should we so cheerfully/desperately try to meet aliens or not, and why?
