The New York Times was here, CNN, they were all holding their stories until the dates came back. And I was thinking maybe they'll come back at 20,000 years ago maybe even 25,000 years ago, and I'll be out of here clean. This is going to be easy. But the date that came back was 50,000--ancient beyond all imagining and right at the limits of radiocarbon. Since then we have OSL-dated the deposit and those dates also came back in the range of 50,000. So we've got it dated two ways, but still the skeptics keep saying that what we've found can't be a human site and that our artifacts must be works of nature because they're so different from the artifacts found at other sites. To which my response is: 'Well... you've never dug a 50,000-year-old site in America, right? There's a first time for everything.
The evidence presented by the ancient maps appears to suggest the existence in remote times, before the rise of any of the known cultures, of a true civilization, of a comparatively advanced sort, which either was localized in one area but had worldwide commerce, or was, in a real sense, a worldwide culture. This culture, at least in some respects, may well have been more advanced than the civilizations of Egypt, Babylonia, Greece, and Rome. In astronomy, nautical science, mapmaking and possibly ship-building, it was perhaps more advanced than any state of culture before the 18th Century of the Christian Era. It was in the 18th Century that we first developed a practical means of finding longitude. It was in the 18th Century that we first accurately measured the circumference of the earth. Not until the 19th Century did we begin to send out ships for purposes of whaling or exploration into the Arctic or Antarctic Seas. The maps indicate that some ancient people may have done all these things.
