A civilization capable of interstellar travel would be a lot more advanced then we are. If we but this in perspective, we as humans don’t really care about other species that much. Imagine a species that is more advanced tham we are compared to chimps. Some people respect chimps, but we keep them in zoos and destroy their living spaces. An interstellar civilization could see us even lower than that, just some primates living on a rock. They might not even think us intelligent, we only just have ‘understood’ quantum theory.
Ye, the civilization might see us as potential rivals even and to be exterminated before we reach their level. It would be very naive to think that any interaction with a more advanced species is gonna be positive for us
