Early in the morning of June 29, 1991, Carrie and Morgenstern were watching the field. Although they could see nothing through the thick fog, they kept their camera running.
By 6 a.m. the fog began to lift. A remarkable pair of circles had been flattened. Stalks (主茎) were bent but not broken. Outside the circles the wheat was untouched. Muddy though the field was, there were no footprints or other marks. The circles seemed to have come from nowhere. “ I can’t explain it at all ,” Mike Carrier said to himself with his eyes wide open.
Carrier is not alone since the early 1980s, more than 2000 circles have appeared in farmer’s fields. Most circles form at night between May and August.
Some believe the circles are caused by deer or some other animals. Others think of UFOs. “The circles are messages given by those who come from outer space,” says Michael Green. “Perhaps they are trying to get in touch with us.”
Pat Delgado has done research on crop circles since 1981. He believes that they are caused by “ some form of earth energy.”
Most scientists think that there’s no scientific basis to back up Green’s or Delgado’s theories. Some of them say, “ We think they’re nothing but hoax(骗局).”
In September 1991, Doug Bower and Dave Chorley told newsmen that since 1979 they had made circles throughout southern England to fool people who believed in UFOs.
Since the early 1980s, Dr. Terence Meaden has visited more than1000 circles. Now he thinks he may have the answer. He believes true crop circles are made by vortex(旋风) which can flatten the crop in circular patterns.
Now crop circles are still found in southern England each summer. Are they really the traces of UFOs?
