I think what Craig meant was that there were no archaeological evidence is that no tomb of HuangDi, or anyone associated with HuangDi, had been found. And without some good old bones to do DNA analysis, modern Western Historians count everything else as fiction.
Ah not only that but there has been no archeological evidence of him, PERIOD.
wether that is the written word. arts (Sculptures, paintings, scrolls etc.), Burial grounds, not only fore HuangDi but for anybody at the time, no remains of cities, organized millitary or bureaucrasy, no desribtions or the like from decendens either, all in all NOTHING. In fact the level off proof demanded by western historins is not unreasonable, otherwise they would have to treat Atlantis and Lemuria as real too. In other words push the idea of true civillation more than 10000 years back whitout any tangible proof, oher than and old mans sayso?.
By the way the oldest regonized city in the world is Cataltoyuk in turkey and that is datet to around 7000BC. But it is still not countet as part of a civillisation, even throu the city is there, and a fairly good sized one too, of around 2000+ citizen.
By the way i votet Shang dynasty as the start, since even in its early period, there is good evidence of rudimental use of most aspects of civillizations, among other things written word for record keeping (Essential) and 'pensel pushers' IE the first bureaucrats.
My motto would be 'Truth will out, but no truth is absolute'.
We all should look for the truth, no matter how painful or obnoxious it might be. but we always have to keep in mind that any truth we find will be coloured by both our self as well as those that createt it. an absolute truth is always impossible to reach since we as species by nature is falible. the greatest danger is when we convinces our self that the truth we know is the only truth that counts.
Worth remembering that truth is not the same as law of reality. IE the law of gravity no matter how it is describet is always as law that counts, likewise all other natural laws, it is only our incomplete grasp of them that can make them seem inconsistent or untruthfull.
