When aliens come to Earth, they often find an empty wheat field and put a logo on it, which the earthlings call the crop circle. Regarding the crop circle, some people think that it is a visual expression of the truth of the universe made by aliens, some people think that it is aliens transmitting some kind of scientific knowledge, some people believe that it is aliens announcing the geographical coordinates of their planet, and some people believe that it is just a "visit here" mark left by aliens out of boredom.
I once asked my alien friends on Zeta, what is the crop circle for? The alien told me that the crop circle does express a cosmology, but it is more used as diplomatic etiquette, according to the cosmic convention, leaving the crop circle is the highest etiquette, only the alien civilization has a high degree of identification with another civilization, will do so, in order to express the desire to deeply integrate with this civilization, in the universe, often see the crop circle as a love letter to a planet.
In the Qianling Tomb of Xi'an, there have been frequent wheat field circles, and here is the mausoleum of Wu Zetian. Zetaxing's friends told me that they admired Wu Zetian quite a lot, she inherited the rule of Zhenguan, and the prosperity of the Kaiyuan Dynasty, and her historical achievements were as bright as the sun and the moon, so they often painted a circle in the Qianling Tomb to praise her. The Zeta people came to the earth from the Qin and Han dynasties, and were captivated by the brilliant Chinese culture, and by the Tang and Song dynasties, the love for the civilization created by this land has reached an unsurpassed level, and some aliens disguised themselves as exotics to visit the Celestial Empire, just to see Wu Meiniang's dignity and hope to develop friendly diplomatic relations with her country.
In addition to diplomatic purposes, crop circles also serve as a means of communicating information. In 1974, you humans sent a message in binary form to the outside of the earth showing humanity, but in fact, this message was quickly intercepted and received, and it did not fly out of the earth at all. The creators of this crop circle are an evil civilization stationed on Earth, and they display the information of our Zeta people in the circle, and they also embellished a string of hieroglyphs, to the effect that we Zeta people are liars, and ask you humans not to believe the technological gifts and promises given to you by the Zeta people. The aliens who sent this message came from the constellation Lyra, and they feared that we Zeta would monopolize the communication channels with humans, so they desperately slandered and slandered us, and did such things in the form of friendly diplomacy recognized by the whole universe, which was very revealing of their qualities.
In addition, crop circles are used to predict the movement of celestial bodies. For example, before the arrival of the star Nibiru in the solar system, there were aliens who created the crop circle, which showed the position of the celestial stars in the solar system when it was first drawn, and in the past two days, the stars on the crop circle moved to other positions, and there was an extra star and marked, this is Nibiru.
In short, the crop circle phenomenon is not mysterious and unpredictable, it is just a way of interaction, as aliens and humans come into contact more and more frequently, sooner or later we no longer need to play dumb riddles by drawing, I believe that the day of our face-to-face communication is not far off.
