Maybe you had been know about crop circle that attract alien (some people claim).
Like this common, uh…I mean things like this.
As written by Wikipedia contributor, we may know that A crop circle is a sizable pattern created by the flattening of a crop such as wheat, barley, rye, maize, or rapeseed. Crop circles are also referred to as crop formations, because they are not always circular in shape. The documented cases have substantially increased from the 1970s to current times. In 1991, two hoaxers claimed authorship of many circles throughout England.
Twenty-six countries reported approximately 10,000 crop circles in the last third of the 20th century; 90% of those were located in southern England. Many of the formations appearing in that area are positioned near ancient monuments, such as Stonehenge. According to one study, nearly half of all circles found in the UK in 2003 were located within a 15 km (9.3 miles) radius of Avebury. Archeological remains can cause cropmarks in the fields, in the shapes of circles and squares, but they do not appear overnight and they are always in the same places every year.
The scientific consensus is that crop circles are predominantly man-made with perhaps some due to meteorological and other natural effects.
But have you ever heard underwater crop circle?
