Good discussion, gang.
As an archaeologist myself (and that doesn't mean I'm above error, just a statement in my defense), let me just comment on this bit, here. I'll leave my views of the Ark for another day (and I think I already posted them in the distant past here, anyway):
2) Archaeology is inherently political; and the results of archaeologists going out into the field to prove something should be viewed with extreme caution. Science is not the practice of proof, but rather of disproof: you take multiple hypotheses into your excavation, and try to disprove as many as possible. The surviving hypothesis/ese are never considered ?truth?, and are always subject to further investigation and revision.
1. Archaeology is not inherently political any more than practicioners of the science allow it to be. The goal of any Social Scientist, as the eminent Mark Bloch once stated, should be to avoid the presence of any bias in as much as it is possible. Therefore, we should do our best to report "facts" and to do our best to recreate an accurate recreation of events, minus the bias of our own religious and political inclinations.
Unfortunately, Mr. Bloch is no longer required reading in most colleges, and ethics are a by-product of an age in Science which is, according to many, best left forgotten.
2. Science is not supposed to be a practice of proof, nor is it supposed to be a practice of disproof. Proof and disproof do occasionally happen, but that isn't -supposed- to be the intent of the practice.
The -real- practice of the Archaeological Method (what later became known as the 'Scientific Method', incidentally), insists that nothing can be proven or disproven without solid evidence. As a result, in -real- science (and I count Archaeology among these, forgive me Physicists and Chemists, among others),
we have very few things that are "absolutely true", and "absolutely untrue". Instead, we have theories, and hypotheses, as your point correctly discusses.
However, how many hypotheses and theories sell books?
Not many.
Everything in "big science" these days is about "absolute proof".
I had a mentor in undergrad who taught me something I've never forgotten.
"Kid," he said, "..if you're going to go out and call somebody a liar, you have to do more in science than just call him a liar. It may work in politics, or even religion, but it doesn't work in science".
In other words, if I am going to criticize someone for violating scientific principles, I'd better be prepared to use those same principles in my own criticism.
So, Hancock is full of baloney? You're probably right. A lot of what he says is full of baloney, certainly. But me saying that doesn't make it untrue. If I really want to say "he's being intellectually dishonest" or "he's completely wrong", from a -scientific- perspective, I actually have to go out, do my own work, and come up with my own hypothesis about why he's wrong.
That's been done with Von Danikken, and it really -does- work. A few wackos still accept the guy as legitimate, but the vast majority of the field has rejected him on scientific grounds; not merely because he's written one too many bad books, and not merely because he has the fashion sense of a blind Visigoth.
So, why doesn't this happen more often? First, because it makes money. There is just as much money in publishing a magazine for skeptics or filming an episode of "Bull****" as there is in publishing "Forbidden Archaeology" or making a documentary about the lost continent of Mu. It's merely the flipside of the same coin.
Second? Because being a critic is easy. While being a scientifically ethical critic is just too damned hard.
Just my two cents.
