Smug? Tree circles first and I then might believe extrawhatevers are doing it.
Crop circles have been explained and demonstrated by humans with rope and boards. Why is it necessary to ascribe them to extrawhatevers? Shouldn’t the extrawhatevers be smart enough to communicate in a manner that might be logical to both communities?
Or are they just interstellar hooligans? In that case, why are their “parents” ignoring us?

You have obviously not read the scientific journals of peer reviewed articles demonstrating:
1. plant nodes being . . . essentially slightly microwaved
2. microfine iron dustings
3. super dried soil
4. seeds from within the circles sprouting differently
5. plants grown from seed within circles significantly more drought resistant.
within the AUTHENTICALLY STRANGE CIRCLES
and
NOT
within the circles obviously hoaxed—hoaxed with strings and boards and obviously very different damage to the plants; NO super dry soil etc.
and such NOT outside the authentic circles in the rest of the field.
It sounds like you are doing so many back flips to avoid a TYPE I ERROR that you are making it certain you will be bludgeoned by a TYPE II ERROR. That’s just inexorably the way that works.
You cannot be unreasonable about a TYPE I error risk without making it more or less certain—at least highly probable that you’ll experience the consequences of a TYPE II ERROR.
I’D WAGER that you haven’t even read half the posts I’ve made above in the last hour.
