I thought fairy circles were rings of mushrooms rather than arrangements of trodden-down crops.
Me too. I came across one last summer on a roadside verge. It was only a few feet across but very distinct. A ring of darker grass with yellowy/creamy 'shrooms dotted around the outside edge.
My 8 year old eldest daughter, who has a vivid imagination and is a voracious reader,wouldn't step inside it.
No aliens involved. Just magic.
