I feel like for interstellar communication or interaction between civilizations. You need to have one of three things:
1) Travel speeds above light speed
2) Wormholes
3) a species which ages very slowly. If their life expectancy is 2000 years, traveling for some hundred years is still feasible

I believe that colonizing planets by any alien is just extremely hard and practically impossible. For example, the nearest planet outside our solar system (Proxima Centauri b) is about 4.2 light years away from us. And right now, our fastest space craft is about 1/1675 the speed of light. That means that we would have to build a space ship that could fully sustain human life for 7035 years while not running out of power to even reach Proxima Centauri, which most likely could not even support human life. And that is THE CLOSEST plant.
