What is your take on extraterrestrial intelligences, have you seen "UFO"s , or even been in one if you lucky and caught by a surprise ? Have you met any people from other planets ? Or simply if you have not, what are your thoughts about the topic, and would you like to have an experience ?
Do you believe in the existence extraterrestrials ? (Belief is based on faith or trust without looking at the evidence, data, mathematical models, that is because your friend saw something, and you trust your friend, without research, that is belief)
Do you understand the existence of extraterrestrials ?
(Understanding is based on collecting data , evidence, mathematical models such as drake equation, astrobiology research etc and deriving a conclusion)
Do you know the existence of extraterrestrials ?
(That is when you have had your own personal experience, scrutinized it to be legitimate experience, as well as comparing your experience with other's evidence data and so on)

I suspect that we will find intelligent life to be rare enough for another example not to presently exist within 100 light years of us, maybe not even a thousand light years. That holds even if there are shitloads of earthlike planets nearby (which I don't believe, really [see my footnote 1]) because of the timing factor. As someone pointed out, an earthlike planet could end up having intelligent life... but it was a million years ago or a million years in the future. Or ten million. Or a hundred million. 100,000 years of existence would be huge by human historical standards and an eyeblink in geological time. Intelligent life could be so rare there are only five species of intelligent life in our galaxy right now... yet this galaxy could have given rise to millions of such cases over time (just almost none of them are still around) and with all the galaxies out there in the universe, that would mean a trillion intelligences out there right now... yet effectively we will never meet them or hear from them. The universe is big and even a staggeringly rare event can happen a trillion times.
 No I don't count just any rock that is less than ten times as massive as the earth and somewhat appropriately spaced from its red dwarf star as "earthlike"--the media way overhypes things. Earthlike? With hideously strong gravity and a year mere days long and so close to its sun a good solar flare would sterilize it? Nevertheless I hope they keep searching; it's possible there are plenty of actually earthlike planets out there and we just don't have the instrumentation to detect them quite yet. Detecting any extrasolar planets at all is a remarkable achievement to someone born in the 1960s who grew up hearing there was no way, ever, to see them.
Recent data from observations by the ESO Very Large Telescope indicate that Earth-like "habitable" planets may be far more common than preciously believed.
Yeah, well, I'm waiting for them to be far closer than previously believed, otherwise it's all smoke.
Extraterrestrial intelligence? Well, if there is intelligence in this cosmos, it would most certainly be extraterrestrial because there is no sign of it here.
We do have extratestoteronial intelligence.
LOL, cool, Robert, I like that! Apparently another word not yet indexed by Google. (But it needs another s: ...steronial.)
This made me think of minestronial soup.
I'm sorry. Can't do crosswords either.
testo= something to do with testosterone?
teronial = ??
I give up.
I believe it is possible for other life to exist out there. I don't think we should go so far as to say extremely possible. I've heard lots of arguments on this topic. Most of these examples of why life elsewhere is so probable is 'time'.
"Life's ONLY been around for a billion years or so and the universe is 13x that!"
Well that's great and all but there's more to the creation of a real intelligent species than just time. So either these other beings are extremely lucky to exist in the first place like us humans, or we got the short straw and for some reason life on earth is so hostile we had to show up late.
Not that I think evolution would very from world to world. Anything is possible though , I guess.
If there is life out there I don't think we should go looking for it. When I was a kid I always thought it would be fantastic and amazing to meet extraterrestrial life of some kind. I don't think that anymore. Odds are they probably wont be very nice.
Back in the 80s, I made the mistake make the suggestion that E.T.s might include "life, not as we know it" ... to a molecular biologist from Caltech's JPL. He was quick to point out that chemistry is very well understood, and that CHON (Carbon-Hydrogen-Oxygen-Nitrogen) chemistry p0ssesses the necessary properties to form the complex multi-valent and relatively unstable compounds that act as building blocks for all life.-- amino acids.
These four elements (especially carbon) are so essential to living organisms, that the entire branch of chemistry concerning carbon based molecules is called organic chemistry.Since carbon, hydrogen, oxygen and nitrogen are very common elements in the universe, as determined by spectroscopic analysis, it is a fairly safe bet that planets with the right characteristics will have some degree of organic life.
It's a COOK BOOK!
