Many have tried to write off crop circles as a hoax setup by elaborate pranksters. However, even attempts to recreate these circles with cameras and media are somewhat disappointing compared to the accuracy, scale, and detail of the unexplained circles. These circles have been found in not only fields of rye, oats, flax, maize, sugar cane, peas, potatoes but also grass, sun flowers, rice patties, and even ice.
However, if these circles are indeed real then other questions must be asked:
An extra terrestrial life form must indeed have the desire to reveal themselves. Why would they chose this format rather than another, for example a book, cloud formation, or direct contact (unless of course there is some kind of alliance which does not allow these beings to reveal themselves)?
What do these circles mean?
Are these crop circles being left by helpful extra terrestrials(Artcurians, Pelidians, Sirians) or perhaps by malevolent aliens(Grays, Reptilians?
