Throughout history there has been an unknown intelligence that has created strange marks, symbols and circles in the fields. These marks were called Crop Circles and their nature escapes human understanding. These agro-glyphs pose answers to questions that humanity has not been able to solve, the intelligence or entity that is behind its formation has important interests that could help humanity. The problem of the Crop Circles, apart from the extraction of its complicated hidden message, lies in the falsification of these. There are groups in charge of distorting the symbols, causing the enigma to be discredited. In the workshop we will show you how to identify the real crop circles of the fraudulent ones and we will inquire about the real message that those builders of the enigma want to transmit to us.
