Structurally they are similar enough that we can communicate. The discovery would be altering our science, but every attempt to exchange beyond technicalities and niceties is somehow incredibly boring to both sides.
After the initial awe, it would be like, yeah, we know aliens.
I think the truth would be that they would be so utterly alien that we would never be able to truly communicate with them and also we would never find them not terrifying.
We bond with inanimate objects and people can find the ugliest animals we can and try to keep them as pets.
We’re such an overly empathetic and social species that I don’t think we will have too much issue wanting to befriend aliens if we could communicate.
more like the aliens will keep us as pets
