Are we moomin, or are we dancer?
There's a ton of science fiction works about first contact with extraterrestrial life, most of which are extremely cliche of "omg aliens are invading". Let's try and avoide that cliche. However given how much effort we put into trying to find life out there in the universe if we were to ever make contact how would you react to the news?
Like several scenarios the most likely is we find life on europa or somewhere in our solar system. How would you react to them finding life in our solar system.
However also how would you react to us finding intelligent life off our planet. Either communicating with them through radio or actually coming to earth.
Also if it were something like the movie E.T. how would you handle being the first person to come across them? Like they don't know anything about the earth and you are the first person to come across them.
And no they aren't here to destroy the earth, humans or subjucate us. Also no not tentacle monsters for our japanese schoolgirls. Also not amazon women from Amazonia here for snu-snu.
Life in our solar system? Amazed and delighted, especially if it was more than goo on a rock.
Intelligent life? Amazed, delighted, loneliness would dissapeare for a long time, bewildered and afraid. As Hawking suggested, what if alien species are colonial and sweep through the universe searching for habitable planets to exploit? You said they aren't hear to subjucate us, but that might be a fiendish lie and you're one of their scouts!
How would I handle ET? Badly.
