What are Crop Circles?

In some places these cornfield formations arise in cornfields just during a year., while returning in England from April to October. 

You can sometimes follow a motive the development of a motives from one year just being a simple circle, and then becoming more and more advanced every year,  

to finally become a hugely complex graphic motif.

In some cases, someone has testified that they have seen balls of light over the field the night before a circle has occurred. The bars in such circles are softy folded.

There are those who see this as s scam and made by people and tried to redo it, but then the straws have been broken off.
