Uberdoink, you seem to be taking an ideological stance against the current scientific understanding of where and when we came from. When someone says "there is evidence to show that homosapien sapien has been around for longer than the current understanding suggests", then there needs to be evidence for such a claim. When somebody points out that your evidence isn't entirely verifiable, or that it is misleading, and you automatically say "that's not right, he's arguing with me", and you defend your claims to the point where they are undefendable any more, well that's an ideological stance.
So what is your ideological stance? Perhaps it is that human history, or
civilised human history, has been around for longer than science claims it to have been. You may be right about that. There have been many worldwide events and disasters that could easily have destroyed all traces of any
fledgling civilisation. I bought an issue of New Scientist today that had an article on how man
could have been using extremely high heat
fiftty thousand years ago to make sharp tools. If true, that would be a pretty amazing discovery.
The sad fact of the matter is that the rule is, with very few exceptions, that the further back in time you go, the more hazy things become, and the more open to conjecture they are. So in that respect, you are right.
But scientific evidence is pretty correct in the sense that it gives us something concrete, something that is subject to peer review, and therefore has it's claims tested often before it is published in a mainstream newspaper. The one thing I have learned from a couple of years of collecting New Scientist every week is that scientists are constantly finding things and musings on the possibilities of such a finding, but also you find voices of doubt (often in the same article), and that's fine because peer review is how science works, and that means that a concensus can only be reached after A LOT of debate and evidence is presented.
Cremo's work, it seems, does not stand up to such scrutiny, or maybe some of it does, but it is buried beneath layer upon layer of anecdotes and questionable results. "Forbidden Archeology", the title, suggests that there is some conspiracy afoot, or at the very least that scientists will scoff at such notions automatically. Well, I can tell you that at the moment there are fresh and lively debates going on about such things at the moment without saying "well, you know, some guy told some guy...". When there is evidence to that favours one theory over another, then that theory will take precidence, but the debating never ends. That is the way of science, and the empirical method, one of the pillars of human understanding.
To say that I believe that human history is older than we currently think it is is OK. I believe that! But do I have any evidence to back up my belief? No. So scientific method rolls on, slowly giving answers to questions, answers which only lead to more questions. And I suspect, but cannot
prove that mankind is slightly older than previously thought.
You seem to think, however, that mankind has to be older than the established view, because ideologically you are against the ideology of the established view.
IMO ideology is never productive when dealing with such matters. It actually reminds me of the whole Left vs Right thing in politics, where each side is thoroughly convinced that the other is completely wrong and only out to screw the other side. When both sides think that, then you're headed for trouble.
Most scientists, IMO, don't think like that, and instead are much more interested in evidence. Except maybe for Richard Dawkins, and he only does it when he steps away from science to talk about God.
