To exterminate us so that we dont have a chance to challenge them could be a motivation.

  Except that the same logic works the other way- what do they have that we would want to mess with them over? The universe is a big place. Looking around, it seems that the endless-exponential-expansion route hasn’t proven popular with anyone yet. There may just be enough to go around.

    Why do we step on ants and spiders? It doesn't need to be rational. All it takes is one sufficiently powerful species to decide "better safe than sorry" and lobbing suitable planet killers at any new upstarts they notice.

      Check out this cool spider they have in Myanmar. https://en.wikipedia.org/wiki/Cobalt_blue_tarantula https://en.wikipedia.org/wiki/Cobalt_blue_tarantula Now that you know it's there, don't you feel like expending the time, energy, and resources necessary to travel there so you can step on it?
