^ Or we can hope that they're simply travelling nomads lacking weaponry due to their peaceful nature that allowed them to progress to the stage that they have, rather than quarrel with their own kind etc. causing themselves to go backwards... Although re thinking that, and on the polar opposite I guess it's likely that weaponry would be a highly developed thing. From the earth's example, many of our inventions and scientific advancements come about during war time...So perhaps for another race to be so advanced for space travel they may, or are likely too, have a extensive history of war/weaponry/take over tactics. Just a thought. edited, hellz yea.
