2012 and crop circles

Some time ago, I read an article about the relationship<strike>s</strike> between crop circles and 2012 doomsday. The most convincing evidence is the one of the latest crop circles displaying the planets of the solar system. As you know, the position of the planets is different at different moments in time. It is also unique in certain periods of time. In  the crop circle below , the position of <font class="Apple-style-span"> the</font><font class="Apple-style-span" color="#0000FF"> </font>planets points to a date : 21st December 2012. As you may know, that is  the last day in Mayan calendar.

It's an interesting topic so I had a research on it. I read several other articles about crop circles. Some of them display circumference ratio and some others display geometric drawings. They're accurate and nobody can explain them. Who made them? What's the real meaning? Some authors consider the crop circles as the signals that extraterrestrial intelligence gave us. They may have wanted to communicate with us or <strike>they want </strike>to give us a warning.

There is a video made by a German (researcher?) . <strike>It collected</strike> He studied many crop circles and tried to translate them <strike>circles</strike>. You may search and have a look <strike>on</strike> at it . It's interesting and amazing.
