At least two logical fallacies have been made here (as i can see).
1. post hoc ergo propter hoc - which means after this therefore because of this. [..]
2. petitio principii - begging the question

If Peratt had matched half a dozen basic shapes, then I would agree with you totally.
As we know, that's why drugs companies have to do trials: a single example of Miracle Drug curing Mr Smith
could be just a coincidence; but if this is repeated on a 1000 people, then statistics helps support the case.
Peratt's field trials include tens of thousands of petroglyphs.
