In 2001, Humanity received a response to Carl Sagans that was sent out to space giving details about Humanity. The message at the time was controversial but the scientist decided to send it anyway. 27 years later Humanity received a message in the form of a Crop Circle that gave incredibly detailed information about the extraterrestrial race that sent it. The crop circle even included a head shot showing the appearance of their species. This crop circle remains the most important Humanity will ever receive.
