Why do you say invaded? I see two outcomes, considering the distance and resources required to make it to another solar-system.
1. They came all the way here to say hello, which they could have easily done remotely and with less effort.
2. They came all the way here to kill us and take our resources, because out of millions of other planets in their range, with more resources, they
picked us because we are so special.
Either way, there's nothing anyone could do.
