Reason similar to another poster. I would listen to what they have to say and decide for myself. To assume because their technology is advanced that they are also spiritually advanced isn't necessarily so. Doesn't mean they are or aren't just because they have managed to cross some hurdles that humans haven't yet.
LOL! I also wonder what some of the other posters have expressed about a greater culture encountering a lessor technologically advanced culture. Poo end of the stick indeed. But one thing that does make me a little hopeful in that regard. To go further than their own backyard may imply that they have settled their own species differences. The resources of minds/intelligence, raw materials, etc. to make space flight possible confound us and we are stymied (or so it seems to me) because of our petty tribal bickering. They would likely be unified in some manner and that is where it can get dark. Are they a hive mind? Are they unified in their desire to conquer as were people/groups/kingdoms/religions in Earth's history? Or have they reached a point in their evolution that they are exploring and acquiring knowledge?
Their reaction should they indeed show themselves will answer the question in no short order. But unlike
Mars attacks or
War of the Worlds scenarios were I an alien race intent on domination of humans I wouldn't land fiddle around play hopscotch with the locals just figure out where the bases of power are and take them out. Remove the obstacles and let the survivors know you now work for us. Any resistance will be met with force.
Scenarios such as
x files and
V (visitors not vendetta) show a slow infiltration of a species and implies that they can't overwhelm humans which may be vanity on our part (plus it makes for good drama) But for me the scariest idea is that they may be more like the aliens in
Aliens. Adaptive, quick, and darn near impossible to kill.
