The Silbury Hill Crop Circle: This crop circle, which appeared in a field near Silbury Hill in Wiltshire, England in 2009, is considered one of the most enigmatic crop circles due to its proximity to an ancient man-made mound. The formation, which features a series of concentric circles and crescent shapes, has been linked to lunar and solar cycles. Bill Steele (November 12, 1999).

Self-Decoding Messages - A very detailed analysis of the original, 1974 Arecibo message, by John Walker

It was pointed out that circles had been starting to appear all over the world and in several locations on the same night, so the claim they had made all of them prior to 1987 was questioned. However most mainstream sources considered the “case closed” on crop circles, despite the occurrence of increasingly complex designs in the decades that followed. This particular formation was obviously not the result of weather: it divided people between those who thought a deeper mystery was presenting itself and those who maintained the simple designs were natural occurrences and the more complex designs must be man-made.

There are quite significant changes to the shape of the humanoid, which becomes almost 'alien-like' and to the diagram of the Arecibo dish. For clarity, I've not bothered going over these in red because the differences are easily apparent. additional NASA or professional radio astronomy confirmations of the EQ Peg signal, apart from Australia). The entire message consisted of 1,679 binary digits, approximately 210 bytes, transmitted at a frequency of 2,380 MHz and modulated by shifting the frequency by 10Hz, with a power of 450 kW. The "ones" and "zeros" were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes. [1] [6]

But, our curiosity was piqued, and we decided to investigate, as we didn't think Colin meant Team Satan - he had someone else in mind. And, it is fair to say, the result of that investigation has taken us completely by surprise. The crop circle is a near replica of the Arecibo message, which contained various pieces of information such as the numbers of chemical elements, the composition of DNA, the position of Earth in the Solar System, and a depiction of a human being. The "answer" itself doesn't expand much upon this and still forms the same 23 x 73 grid (because these numbers are primes) and most of the chemical data remains the same. The changes to the message to create the response are straight from existing alien folklore and science fiction. In the section detailing important chemical elements, the main focus is altered from carbon to silicon, and the diagram of DNA is re-scribbled slightly. At the bottom, the pictogram of a human is replaced with a shorter figure with a large, bulbous head. This is a clear reference to the "grey" type of alien, and as a depiction could only be something that a human came up with.
