We humans have often been raked over the coals by super-beings who either see little of worth in our species, or have no doubt that we're slowly but surely extinguishing ourselves. Often it's hard to argue with their conclusions; after all, while we're given the impression that we're hearing an objective point of view, it's actually a human who's giving them their words, and that's about as first-hand as you can get when it comes to pointing out our failings and the prospects for our survival. But the notion of someone or something not of our world providing us with a frank assessment of us and where we're likely headed has always been a fascinating one, regardless. And if there is alien life out there capable of interstellar space travel, perhaps the fact that they've chosen to give our world a wide berth after looking us over speaks volumes.
Yet given our focus at the PPoC, it might be interesting to dip into the fictional world of comics and get a sampling of how Marvel's other-worldly characters see our prospects for continued survival. Most of these beings don't have our best interests at heart, of course, so their opinions on the subject can be rather pessimistic--yet you may find yourself feeling that the points they make are difficult to refute.
Jeez, Surfer, don't sugar-coat it--tell us how you really feel!
