The Crop Signals Project Created
The Crop Signals Project Created

With this timeline considered, it’s time to accept that there is a high probability that we are not alone and that what we refer to as the crop circle phenomena is in fact and attempt by a higher intelligence to contact humanity. As this hypothesis is becoming increasingly more like to be proven by the day, it was time to jump ahead and start building a resource around the concept and begin decoding and deciphering these most curious and inspirational designs to help advance humanity.

2009
The Signal Device Mechanism
The Signal Device Mechanism

This incredible formation appeared in 3 parts in just over a week and seems to depict some kind of device (first 2 parts) projecting a strange language or pattern that we think could be the device used for making the crop circles.

2007
Sacred Geometry Atom
Sacred Geometry Atom

Yet another stunning expansion on the sacred geometry pattern, this one showing 2 rings of 20 cubes around the seed and 4 layers of interference triangles radiating the outer ring. This one appeared near Sugar Hill, not far from Barbury Castle. Interestingly 2 years later in 2009 scientists published the first ever image of an atom which resembles the pattern.

2001
Arecibo Message Response
Arecibo Message Response

This is precisely what we would expect to receive as a message from an extra terrestrial source – a reply to a radio message broadcast by SETI in 1974 as a hello from humanity to the stars. Close to 31 years later in 2001, this crop pattern appeared in a field beside the Chilbolton Observatory in Hampshire, UK. This response time could indicate that the sender inhabits a star system around either 30 light years away if their method of communication operates instantaneously or 15 years light years away if it is limited to the speed of light. The response contains various clues as to who or what they are: biologically they are silicon based instead of carbon based with an extra strand in their DNA, they are significantly shorter than us with larger heads and they inhabit 3 planets out of 8 planets either in their star system or in our own as the solar system depicts 9 planets including a ring for Saturn and the gas giants highlighted as such. They use the same mathematical system as us and have an overall population of around 30 billion. Most curiously we also have at the bottom a depiction of the device used to broadcast the message which also appeared as it’s own Agrogram the previous year in 2000.

1990
Carbon Lifeform Agrograms Appear
Carbon Lifeform Agrograms Appear

One of the most common Agrograms is the 4 fold circle formation, it was also one of the first formations to appear in the crop circle lexicon and one the first to appear in the new millennium.

Hello Hydrogen
Hello Hydrogen

Often appearing in crop circles at the beginning of the year as a hello and establish communication with intelligent life. Depicted as a hydrogen atom or cell this is most likely used as a greeting sign from other intelligent lifeforms in the universe. SETI scans the hydrogen line radio frequency of 1420mhz, which is the same frequency emitted by accelerated hydrogen atoms (the most common element in the Universe) and is therefore thought to be a frequency on which intelligent beings might use as a “Hello” signal. Interestingly the famous “Wow!” signal was hypothesised to be of alien origin because it was at this frequency at high intensity. The┬áPioneer plaque, attached to the┬áPioneer 10┬áand┬áPioneer 11┬áspacecraft, portrays the hyperfine transition of neutral hydrogen and used the wavelength as a standard scale of measurement. For example, the height of the woman in the image is displayed as eight times 21┬ácm. The 21┬ácm hydrogen line is a favourable frequency used by the┬áSETI┬áprogram in their search for signals from potential extra-terrestrial civilizations. In 1959, Italian physicist┬áGiuseppe Cocconi┬áand American physicist┬áPhilip Morrison┬ápublished “Searching for interstellar communications”, a paper proposing the 21┬ácm hydrogen line and the potential of microwaves in the search for interstellar communications.

1979
Crop Circle Phenomena Emerges
Crop Circle Phenomena Emerges

Colin Andrews coins the term crop circles. Many of the first circles are only described by witnesses, commonly up to 5 circles.

1678
The Mowing Devil
The Mowing Devil

The Mowing-Devil: or, Strange News out of Hartford-shire is the title of an English┬ápamphlet published in 1678. The pamphlet describes a night following a dispute with a neighbour, a farmers field appeared to be in flame. The next morning, the field was found to be perfectly mowed, “that no mortal man was able to do the like”. This pamphlet, and the accompanying illustration, are often cited by crop circle researchers as among the first recorded cases of crop circles. The crop circle phenomena is also commonly associated with glowing light “orbs”, which in 1678 would have been described as “flame” as this was the primary source of light at the time and lends further credence to the crop circle association.
