So, nobody has ever witnessed the formation of a large tree structure by a windstorm or ice/snow either, am I right? And this means there is no "evidence" of that happening either, am I right again? Sweet! I'm down with that.
Bring the evidence that random meteorological events cause these. Until you do, I'm going to rest my case on "huge, strong, furtive bipeds with hands that have been observed doing just about anything a biped with hands can do".... and as I mentioned, there have been accounts of contemporaneous tree manipulations to sightings, and some very close in time and proximity. Above all else, those in opposition to this idea have proposed no other reasonably plausible explanation, which for now is exactly the same as not having the explanation.
Why this is such a giant leap in logic for some is beyond me. They are not assembling fusion reactors in the woods people, they are apparently just piling up trees for reasons only they can know. Bring a better hypothesis than "I don't think they are" and we'll talk. In the meanwhile, you are no better than the scoftic, who, when asked to explain BF sightings and footprints only says, 'I don't believe in BF". No. Better.
So, again. Looks like I stand unchallenged on any serious level. The only rejoinder you have, I guess, is these structures don't exist. But they do. Deal.
