As is tradition in archaeology.
So saying, "archaeologists are doing it" is demonstrably untrue here.
You just won't find them in HN comments for obvious reasons.
You incorrectly stated that's a tradition in archaeology, as if that would make any difference. It's not how theories are meant to be formed from evidence, regardless of whether or not you think it's a tradition in archaeology (which it isn't.)
Explicitly so, given that the root of this thread is saying it is a theory that they 'like', not that they think is objective truth.
