If they think anything like us, they will either: see us as a potential future threat, and preemptively bear their fancy sci-fi weaponry upon us, probably annihilating us and using the survivors as indentured labor for their new fancy colony; or see us as a way to profit off our resources, and only contact our leaders to keep the wheel well greased for everyone involved
Maybe they could be nice guys like the Federation in Star Trek, just waiting for us to become an interstellar-capable civilization to welcome us with open arms. Or maybe, like
>>13606766 said, we will be like gnats to them, and unless we pique their scientific curiosity, or they need to mine our planet, they will pass by
We tend to think they would go the piece-of-shit route because that's what we'd do, but we can't really say how a different species would evolve differently from us, even psychologically. For all we know, the concept of wars could be totally alien totheir mindset.
It doens't matter. There's probalby no such thing as an interstellar civilization. The distances involved, and the physical constraints on any engine needed to reach even a fraction of the speed needed to cross them, are jsut too high.
