• Yes. You can find it in the literature, music, art, et cetera.
  • None whatever.
  • yes +5
  • Hopefully some answers to this question could hint at that (I assume the answerers are from there).
  • Not much, but a trip to Florence and Venice to see the art of the Italian Renaissance can restore one's faith in the possibility.
  • Yes, but it's waning.
  • Probably not - all the SETI radio telescopes point outwards :)
  • Yes, without a doubt. They can be readily recognized as those individuals who do NOT: ...ask if they could be pregnant after bl*wing their boyfriends and rubbing their man-goo all over their Va-JJ's, ...ask what it means when they glance at someone and catch them looking, and then they quickly look away, only to return the look out of the corner of their eye. ...ask if they should stay or leave someone who repeatedly cheats on them, verbally abuses them, physically abuses them, or doesn't pay any attention to them. ...go around disrespecting other people's faith, sexual orientation, or dietary preferences. I'm pretty sure there are a few other disqualifiers out there...
  • Not a lot but we are hopeful....
  • for as long as I'm breathing there is.
  • Depends on what you mean by intelligent. A cockroach is intelligent compared to an earthworm.
  • No. Well, at least not in some parts of Kentucky.
  • There doesn't seem to be, does there?
  • There is but it has to be far away from public buildings, especially those inhabited by public servants.
  • This is an interesting question. Standing on the Earth in a big city, there would be definite signs. Flying at 30,000 feet over a large city, you'd be able to tell quite easily. From an observatory on Mars? Well, maybe not right away. You could see that the Earth has a lot of water, and you might guess that it has life on it. If you tuned in on the tv, radio and microwave bands, you'd see all kinds of semi-intelligent ;-) activity. However, if you are at a vantage point, say 100 light years away, even though radio was being broadcast that long ago, it probably wouldn't be powerful enough to be able to detect it above the background noise from our neighboring star. If you had really good instruments, though, you might be able to detect the water in our atmosphere and perhaps that we have liquid water oceans, and guess that there might be life there, but you wouldn't know much more than that. On the other hand, this is the sort of knowledge we can obtain about planets orbiting other stars today. In 100 years, perhaps we will have vast arrays of telescopes in space which can gather much more detail about distant planets via very long baseline interferometry.
