There's something about these nutters that always strikes me as a blatantly flawed premise in their thinking: [quote]We have a long history of UFOs and of course there has been a lot more activity in the last few decades, since we invented the atomic bomb and they are very concerned about that and the fact that we might use it again, and because the Cosmos is a unity and it affects not just us but other people in the Cosmos, they are very much afraid that we might be stupid enough to start using atomic weapons again, and this would be very bad for us and for them as well. [/quote] Yes, Aliens capable of interstellar travel, and thus capable of destroying our entire planet by essentially throwing rocks at us (accelerate a large asteroid to a fraction of the speed of light, aim it at Earth, and there'd be nothing we could do) are afraid of our weapons that are likely to have orders of magnitude less energy output than their engines alone (assuming they got here in a reasonable amount of time). Whenever I see a group claim that aliens are afraid of or are even interested in our nukes, it strikes me as the projection of what is so obviously a completely human concern that I have trouble realizing why these people can't see that. Not that those groups have any credibility anyways, I'm just saying even their sci-fi fantasies are shit.
