"Either way what really counts at the MPP excavation was all the stuff painstakingly uncovered in the hot sun by the students, etc, and the report that will come out several years hence as to the dating of the pottery, bones etc. It might come with a theory attached but at least it will have some backup......."

How true. No-one ever dug up a theory, only evidence. But maybe we're too hard on archaeologists, constructing theories on the basis of a couple of facts, or one - or none - is hardly unknown around here. I guess though if they'd preface everything they said with "one possibility is that..." it would take the heat out of it.
