Crop circles are large patterns created by flattening crops, typically in fields of wheat or barley. These formations can vary in size and complexity, ranging from simple circles to intricate designs. They often appear overnight, leading to speculation about their origins, including natural phenomena, human activity, or even extraterrestrial involvement. While some crop circles are confirmed to be hoaxes made by people using simple tools, others remain unexplained. Researchers study these formations to understand their impact on agriculture and local communities. Despite the mystery surrounding them, crop circles have become a popular subject in popular culture and paranormal discussions.
