Think!
If you were from a technologically advanced civilzation many, many light years distant from here, would you waste you time on this violent collection of scientific wannabes, when in all probablilty there's so much more to be had out there?
How could you trust a "civilization" that is brutal to it's own?
How could you approach a people who have seen fit to irridate their own planet - not just once, but many times?
How comfortable could you feel with an ignorant mass of collected races that seemingly have been thrown together haphazardly, and can't find it in themselves to get along?
How confident would you be with a world that has just scratched the surface of scientific possibilities and whose first option to your visit is more likely than not going to be militaristic?
With each passing year I become more and more convinced we live in a really bad galactic neighborhood, and until such time as we get our sh*t together, we won't be graced with a visit from these guys any time soon.
And in passing, I don't think warp technology is the answer to interstellar apace travel. At some point it might serve as a semi-useful bridge technology, but I really think they'd use something else more efficient.
Just my thoughts...
CA....
or maybe Alien Boy Scouts, err Person Scouts.
Or maybe the opposite is true. We are the peaceful, ecologically sensitive ones that ate technologically superior by comparison. One civillization must be the most advanced. It could be us.
