They created their own crop circle using the same method as Doug and Dave, and then watched as two different kind of people came to the place:
- the "New Age" folks with their pendulums, rods, measuring "vibrations" and reading "energy" with the help of "quantum physics"
- the skeptics
The "New Agers" concluded it was made by aliens and "energies" (both amusing and cringeworthy to watch), the skeptics didn't fall for it and concluded a human creation, like every crop circle they've analyzed so far.
Now, when a crop circle appears on the Moon or a highly unreachable place, when it's drawn on a field with no grooves to hide the steps, then we might be on something. In the meantime, it's just glorified street art.
