Now the discussion becomes really interesting.
I for one think that if alien life forms exist, they would be similar to us to a certain degree, as physics and chemistry follow the same rules everywhere in our universe. Thus, life's origin where it is possible would be quite similar to the first forms of life here.
So it would also develop in a similar way. Of course, aliens wouldn't just be the same es we are, because there are loads of factors which decide which branches of life go extinct and which develop further, but the basic recipie of a sentient being would be the same throughout the universe: it would have to have nimble tools for delicate work, a well performing brain and means of communicating with one another on a level that allows talking about abstract matters. So I think that sentient life is actually quite alike in our universe.
Another thing is taking the latest quantum physics theories in account: in universes with different laws of physics, life of course would be radically different.

Yep, you are right. The universe is too large for the correct chemical soup required to start and maintain life not to be created in another location. It is more a question could they ever reach us due to the distance
Who is to say that the correct soup all came together a billion years ago in another system, and they have had a LOT longer than us to evolve and develop, and have not invented interstellar travel?
Hypothetical...imagine popping back just 500 years into our own past with you present day knowledge...you would either be hailed as the brainiest person alive (eat your heart out Steven Hawkin!) or burnt at the stake for witchcraft!
As for crop circles, just ask Mulder...he will tell you that he WANTS to believe!
Also: SIGNS
You guys talk as if the development from microbial life to intelligent beings is inevitable.
Life on Earth has existed for 3.5 billion years, and has fared pretty well without intelligence for 99.99% of that time, and without interplanetary flight for 99.999999%. And it remains to be seen if we won't drive ourselves into extinction before we can reach beyond our solar system.
Actually, yes, if there isn't a massive global catastrophe that renders a whole planet inhabitable, intelligent life is going to be spawned sooner or later, as it is one thing that makes life different to dead matter: it evolves.
Of course, the intelligence achieved will be different in quality depending on how harsh the environment is.

Some crop circles are fake, I can't say how many and I can't say they are all fake. I live very close to a crop circle site... or at least it was... until two guys got caught one year with a shopping trolly and a length of rope in the middle of a field attempting to make there annual mark on the farmers crops.
Greenseed, that is one of the fictional crop circles that these men got charged for, the location was crab wood farm house, near Winchester, Hampshire.
Here are two other fake crop circles from around the Winchester area, actually know the copy cats who did both of these, lucky for them they did not get caught and charged with criminal damage!

What is a "fake" crop circle exactly? I'm sure someone asked that already.
If someone can be caught and charged for doing it, that makes it "real" because it's real crops and real circles therein. And personally I reckon if aliens are intelligent enough to find our planet and make their way down here undetected, they probably have better things to do with their time than draw on our plants.
Think about what our space travellers would do if they went to another planet.
"Control, we are entering the atmosphere now. All systems appear to be stable."
"Roger that, proceed with caution. Let us know if anything changes."
"Control, I can see signs of life. I repeat, I can confirm signs of life. Domestic and commercial buildings, artificial light sources."
"Excellent news, guys."
"We have landed safely."
"Fantastic."
"Control, I am now stepping out of the craft."
"Wonderful."
"Control, I am now dancing around naked, drawing graffiti on this field. Later on I'll whip our ship around in random shapes in their night sky. Our journey has taken many years and millions of credits to complete. Let's bugger off before anyone can confirm we were actually here. Weeeee."
"Umm..."
To believe that we are the only things alive in the infinite space in the universe is nothing short of arrogant.

Surely the whole idea of crop circles was to dupe people into believing they are not of this planet? Was it an alien craft landing, was it something beamed from space? Fake was probably not the best word, lets remove it and replace it with hoax. Most of these are 100% hoax, If it is not a hoax I am sure more than 0 people would like to make claim to fame over there artistic work.
To me crop circles = people on mowers having fun with their latest GPS toys... 
(at least the recent, more clever ones)
(at least the recent, more clever ones)IMO because physics and chemistry follow the same rules everywhere in our universe aliens can turn out to be totally different. We are water based life forms on a planet that has just the perfect size and atmospheric conditions so life forms of our type can evolve here. Sn alien planet can be ,let's say, 3 times bigger then ours, with very chaotic atmospheric conditions, we could say that the aliens might turn out to be carbon-based life forms thus their basic recipe of a sentient being totally different from ours.
"it would have to have nimble tools for delicate work". Delicate work is a very relative word when we think about it's possible applications in the universe, isn't it? In my example, the carbon-based aliens on their planet 3 times bigger then earth would move very very slow compared to us, our definition of nimble and normal would be their definition of Godly fast and nimble.
"a well performing brain'. My example would have a very rudimentary brain, yet they would be on top of the food chain on their home planet.
" means of communicating with one another on a level that allows talking about abstract matters". Could you please define abstract matters? It's yet again a very relative term.
IMO Crop Circles can't be called fake or real, just hoaxes .You made a mistake their. You presumed that aliens might have a few human features but as I said before, they can be totally different, thus their understanding of communicating with another race might be totally different from ours.

Apparently so, if you believe that first image posted is a real crop circle. According to that the aliens understand both ASCII and English. Which kind of makes me wonder why they just don't use billboards and spray cans like everybody else? :ufo:
I think there is another factor that not everyone considers, which is time.
Think about it: mankind has got some sort of "advanced" tecnology like artificial light for only a couple of hundred years, while the universe exists for fore than ten billions of years. What are the odds of another lifeform to be in a somewhat similar state of tecnological evolution? Wouldn't it be far more likely they'd be "beyond" of us, or "ahead" (whatever that might be), for that matter.
Now I don't know if I have made myself understood (not likely), but I'm tired as hell.

First of all, there seems to be only a very tiny margin in which complex life is possible, thus I still think that higher developed species had all pretty much the same environment, thus leading to very similar developements.
And I too would assume that there are life forms that are higher developed than we are, and also ones that are lower.

Every star is another sun, for every sun there is another group of planets.... logically a life form must be out there some place! One day we will find it, until then we will never know. I think too many people are influenced by sci fi books and films and there for all assume that aliens are of a specific size, have black eyes and walk on two legs. If something purple with 6 legs, 4 eyes and 9ft tall was to turn up one day, im sure we would all think it was just a freak of nature or a newly discovered species. As long as I don't get abducted and probed... I hope there is another life form. The chances are that were not alone.
We're also carbon-based life forms
It's far less likely for complex life to evolve on a planet 3x the size (or mass?) of Earth. If gravity is too strong or too weak life will have trouble evolving. If the atmospheric conditions aren't right; same issue. The thing is that our planet is floating around in what we believe to be the perfect zone for live to start & evolve on. Not hot enough to make water boil, not cool enough to freeze (the majority of) it, an atmosphere and ozone layer to protect from radiation and keep the heat in. Life might exist on much less habitable planets, but that life is far less likely to evolve into sentient beings because of the limitations of their environment. Limitations of scale prevent something from living on huge planets with many times the Earths gravity.
The other points mentioned have all been thoroughly speculated on by anthropologists, physicists and biologists. The general concensus is that advanced alien life indeed needs to have the following functions:
- Sight (or any variation advanced enough to work as good)
- Communication
- Ability to manipulate tools
- Curiosity (if we'd all stayed in our caves, nothing would've happened)
That leaves us with the knowledge we have from our own planet to start thinking about the way aliens might look, and we almost always end up with the same basic features that do resemble humans. Yes, it would be really cool to see a 9-footed lion with claws in his mouth and wings on its back, but it's impractical and evolution (as we believe it works) should always move to roughly a symmetrical being with arms, legs, hands and a head. Variations are possible, but I doubt that if we find life in its biological form (the species may have integrated entirely with its own technology and become a completely different species) that they are much different to ourselves.
Oh, and more on topic:
Crop circles are definitely real, but I really doubt that they are extraterrestrial in nature
There is also the chance that we wouldn't even recognise something as life if we saw it. Just because we're carbon-based down here doesn't mean that in a different system under drastically different conditions with a sun spewing whatever kinds of radiation you like, you wouldn't end up with silicon-based or something instead.
We wouldn't look at it and necessarily see a recognisable living organism, but it would be.
Remember, everything we've based "life" on only goes as far as what we can identify and prove. Anything off-world (and certainly out of our system) is anyone's guess. Just because rules apply here doesn't mean the same ones will elsewhere.
Giant crystal squid-monsters FTW!

Yeah but look at the contrast of possibilities on just one planet...
exhibit A
Exhibit B
If the 'grays' ever turn out to be real then I'll seriously feel ripped off.
Well, they are actually quite alike, those examples:
carbon based
oxygen fueled
good visual perception
nimble tactile organs
quite intelligent
The only difference I see is that one is a tool-user and one isn't. That doesn't mean though that squids could evolve into doing so.

I just wanted to point out that they don't really look alike. The 'greys' look more like us than some of us look like us! 
I bet they're both slimy Not the Greys...
Not the Greys...Is that really a species of this planet? They don't look very human!
Those are called Boybandus Singerus. They are a sub-species of the human race whose only purpose is to make female teenagers scream very loud, to make humans pay for horrible music, and to occasionally get drunk (or stoned) and make a sex videotape of themselves
Oh, I understand a little more, however, I still have much to learn about this special species. Seems a little like a cross between a Spider (making the girls scream) and a normal student (and to occasionally get drunk/stoned) type rodent. Maybe I should avoid these Boybandus Singerus things, they sound deadly!
