Zeroth contact?
I'm no astrobiologist, but if you'd asked me what sentient life on other worlds would be like, I wouldn't have said human.
But here we are.
I mean, not just humanoid; actually literally human, according to the message.
How long have they been there? How did they get there? Were they put there deliberately? If so, by who? Why?
We've found life on a planet outside our solar system, and we're still not sure whether or not we're alone.
I really don't know how to feel about all this.
