You say you've read countless books by experts about these things and I am just wondering what makes someone an expert on crop circles. How does one become an expert in that field ?
Is there a course for this at the university ?

Way to go aliens. If they're out there they are freaking jokesters and fools. This amounts to a cosmic, ringing the doorbell and running away.

The message was sent during the dedication of a major upgrade to the Arecibo radio telescope in Puerto Rico on the afternoon of Nov. 16, 1974, and contained some very basic information about the human race. It included representations of the fundamental chemicals of life, the formula for DNA, a crude diagram of our solar system and simple pictures of a human being and the Arecibo telescope. "It was strictly a symbolic event, to show that we could do it," explains Donald Campbell, Cornell University professor of astronomy, who was a research associate at the Arecibo Observatory at the time. Arecibo Observatory is operated by the National Astronomy and Ionosphere Center, managed by Cornell University for the National Science Foundation. The real purpose of the message was to call attention to the tremendous power of the radar transmitter newly installed at Arecibo and the ability of the telescope's 1,000-foot diameter dish antenna to project a powerful signal into space. But many of those present took the event seriously, according to Harold Craft, Cornell's vice president for services and facilities, who was then director of the Arecibo Observatory. "We translated the radio-frequency message into a warbling audio tone that was broadcast over speakers at the ceremony. When it started, much of the audience spontaneously got up and walked out of the tent and gazed up at the telescope."

Prof Says Beings From Outer Space Have Visited Earth Associated Press, November 26, 1962
LOS ANGELES. (AP) - Some of the best scientific minds in the country were stumped when a slender, dark-haired young man chalked on the blackboard this equation:
N equals R FP NE FL FI FC L.
The speaker was Dr. Carl Sagan, a 28 year-old assistant professor of astronomy at Harvard University.
His audience consisted of several hundred members of the American Rocket Society, gathered for his luncheon address. The equation was his way of expressing the mathematical probability that intelligent beings from outer space have visited earth.
Sagan soberly explained that in his equation N Stands for the number of advanced technical civilizations in the universe possessing the capability of interstellar communication.
R is the mean rate of star formation averaged over the lifetime of the galaxy.
FP is the fraction of stars with planetary systems.
NE is the mean number of planets in each system with environments favorable for the origin of life.
FL is the fraction of such planets on which life does develop.
FI is the fraction of such inhabited planets on which intelligent life with manipulative abilities rises during the lifetime of the local sun.
FC is the fraction of planets populated by intelligent beings on which advanced technical civilizations rises.
And L is the lifetime of this technical civilization.
Sagan said information in his formula is based on current estimates by astronomers. In making calculations, he assigned each symbol an arbitrary numerical value. As expressed in numbers, Sagan said, the formula means that at least 1 million of the 100 billion stars in our Milky Way galaxy have planets which have developed civilizations capable of travel between the stars.
"Let's say that each of these civilizations sends out one interstellar expedition per year," he said. "That means that every star, such as our sun, would be visited at least once every million years. In some systems where these beings found life, they would make more frequent visits. There's a strong probability, then, that they have visited earth every few thousand years.
"It is not out of the question that artifacts of these visits still exist or even that some kind of base is maintained, possibly automatically, within the solar system, to provide continuity for successive expeditions. "Because of weathering and the possibility of detection and interference by the inhabitants of earth it would be preferable not to erect such a base on the earth's surface. The moon seems one reasonable alternative."
"Forthcoming photographic reconnaissance of the moon from space vehicles - particularly of the back - might bear these possibilities in mind." At a news conference Sagan predicted man himself would be capable of interstellar flight at close to the speed of light "within a century or two." Asked if he believed in flying saucers, he said: "I do believe there are objects which have hot be identified."

Whenever I see disinfo at work (see above) I know we're on to something.
And here's meat and veg of it all.
An opposing view us not disinfo, please act like an adult and take on criticism with maturity.

Excellent post OP.
I need to read it again slower and cross-reference with some other material before I can comment further.
S&F for you.

Besides which, if they were so close why wait so long to respond? Sagan was left hanging for an answer I guess, pretty rude of the aliens.
Sorry, but it doesn't ad up. Sure whoever created the "response" needed to have a lot of scientific & biological knowledge... but these ETs would have impressed more with a quicker answer because after 27 years some bright folks with the internet could have came up with it.edit on 1/25/2012 by RedParrotHead because: typo

I disagree, all it takes is planning, it's not like the makers were out there nutting it out as they go. Once the complexities are sorted out on paper beforehand, the crop circle is the easy bit.

Don't know about all of this post, but the part (above) about the solar system depiction caught my attention...
The reply, showing Earth, Mars, and Jupiter raised up, AND Jupiter "glowing" made me think of *2001: A Space Odyssey*! Recall in the sequel, "2010", Jupiter is turned into a new "sun" so that our system becomes a binary star system. This could also (maybe) make Mars habitable. To me this looks like what the reply is showing us...
My parents were not scientists. They knew almost nothing about science. But in introducing me simultaneously to skepticism and to wonder, they taught me the two uneasily cohabiting modes of thought that are central to the scientific method.
AM: Did Carl Sagan collaborate with you on designing the message?
FD: Carl Sagan wasn’t part of that, actually. It was constructed by several of the scientists on the staff at Arecibo, but mainly by me. But Carl Sagan did play a role after it was constructed. I took him to lunch one day and presented him with the message already decoded. I asked, “Can you understand this?” This was a test to see if the message was understandable to a very knowledgeable Earth scientist. We eventually learned that nobody could interpret all of the message; each scientist only could interpret the part relevant to their discipline. So Carl got the numbers right and the planetary system right, but he didn’t get the DNA chemistry.
