Haha. I do not at all presume we are alone. I think you are assuming much of me. Obviously, a nerve was struck. When it is shown that UFO proponents do not really know what they are looking at they always attack the person making sense of the phenomenon. Yeah, I'm a small-minded, asshole. Sure. Because people like me have actual standard of evidence we are called close minded. It wouldn't be hard to convince me that we have visitors. Fucking think about it. What would it take to convince you otherwise, eh?
Everything I just wrote was in reference to this specific case. I do think there is a possibility of other life out there. Or that maybe there was at one point, or will be in the future else where in the universe. The fact of the matter is that the universe is sooooo big, soooo inhospitable to life, the stars soooo far apart, and that the energy requirements for interstellar travel are astronomical. Even by the time a civilization embarks outside of it's own solar system the species which could exist at their destination would likely become extinct before they ever made it. Or the the solar system/planet destroyed by it's sun. The universe is not static, but constantly changing, expanding and growing further complicating things as time progresses. You have to think in the big picture and not just let that human need to feel connected and to not be alone cloud your (and our) judgement.
I wish it were true, that aliens are visiting us right now. But the "evidence" currently being presented is laughable. It's the same old "proofs" over and over which were shown long ago to be completely unreliable. That kind of stuff never makes it to the news. Sensationalism gets people attention. Dry scientific inquiry does not. Simple as that, really.
I could go into a crazy amount of depth here, but I won't. People who believe this stuff don't believe because of a logical or reasonable argument, but a deep-seated need to feel connected to the universe. I'll just snag this little bit (from a HUGE post =) I posted from a discussion on ss.org about alien visitors.
- "About the time thing, and alien visitors. You have to examine the large-scale while contemplating this. The universe is about 13.7 billion years old. The earth is about 4.5 billion years old. The Milky-Way galaxy is 100,000 light-years across. We are still a very young species. Using the earth and the Milky-Way as controls, let's assume that it would likely have taken another solar system a similar amount of time for intelligent life to evolve (or be seeded...oh, i keeed, I keeed...). The distance between galaxies is huge. Not to mention that the galaxies are all being "pulled apart" from each other because of the expansion of the universe, which is also accelerating faster and faster as their distance from the point of expansion increases. As far as we know, it is not possible to reach or break light-speed. It would take more energy than is contained within the universe to make a speck of dust reach the speed of light. There do no *seem* to be any planets in our celestial back-yard that are capable of harboring life, let alone evolve intelligent life. That suggests that aliens making it here would have had to transcend time and space. So in the case of time-scale, it is highly unlikely that anything has ever visited us in the past. That does not rule out the future, though. As time goes by it only becomes more and more likely that we will encounter life. It is less likely that we were visited as you go further back in time."
"Oh yeah, then there are the proponents whom, when confronted with the fact that all life on the planet shares bits of DNA and claim that it's only a coincidence that we share DNA, that say that all life on earth evolved from these alien seeds. So, I guess we can go back about 1.5 billion years before us, when life started to emerge on our rock... Making their visitations even less likely. So, where would these aliens have come from? were they seeded as well? Were they sneezed out of god's nose into this petri dish we call the universe? Am I high right now? :/"
