Crop Circles.

discreditedanomaly_regionPhysical Trace & Crop Circles

Phenomenon documented; ET/paranormal origin discredited. Canonical example of a 'physical anomaly' that is human art/hoax.

[DEEP DIVE 2026] Honesty split: the PHENOMENON is real and its MAINSTREAM CAUSE is human [DOCUMENTED] - Bower & Chorley's 1991 Today-newspaper confession (200+ formations since 1978, ropes/planks/sighting-cap, inspired by the 1966 Tully saucer nest) + the circlemakers land-art collectives (complex pictograms by hand overnight). Geography confirms human access (near roads/heritage sites, overnight, correlates with media coverage + no fencing). Hypothesised natural causes: Meaden's plasma vortex [COMPETING-EXPLANATION, abandoned]; Levengood/BLT biophysical claims [DISPUTED/DISCREDITED]; ET/UAP origin [ALLEGED/FOLKLORE, no scientific evidence].
