Crop circles were a popular topic in the late 1990s and early 2000s, but now they are rarely discussed. Crop circles are not evidence of #alien visitations, but rather a type of landscape #art created by humans.

The history of crop circles dates back to the 17th century, with various explanations for their appearance. In 1976, two Englishmen admitted to creating crop circles as a #prank, which gained widespread attention and led to the replication of crop circles worldwide.

Despite the evidence and explanations, some believers still consider crop circles to be evidence of #extraterrestrial activity.
