what do you think about the famous crop circles?

well i know not much information about the famous crop circles......but i know that they exist and that they are quite mysterious about how they may have been formed.imagine this story
u are a farmer and you own a big farm in a village in england.you are happy to own the field and have grown rich by the maize it yields.next month the crops are grown fully and u r harvesting them.all your family are ready for that.today,like a routine you visited your crop field to see if the irrigation is right.u ve eaten ur dinner after working in the field...watching the irrigation and managing everything.tomorrow morning also u wake up ,have ur lunch and go to the field to see it,to see the irrigation,to manage the birds,insects harming you.......alas suddenly you see a path formed ........its a big one .......its somewhat curved.......u inform the police.......a police helicopter comes..........and as they come to u ....u see their surprised faces....they force u to get in the heli..........as u go up you find that its not a mere path its a whole circle and its beautiful one .......looks like someone very big has made a drawing in your field and the guy is an artist......
now u imagine how this monsterous art can be formed in a single day by a human.....
was it god?or an alien?or some ghost or some secret aircraft of the us army that has landed and made an impression.
