This is an important piece of data and conforms to my expectations regarding global cultural sharing that took place during the high Atlantean Age between 2500 BC through 1159BC. Please note that we have reason to expect continued links both well before and long after. What was lost however was the pressing economic rational of the metal trade.
Our problem by the by will not be lack of evidence so much but eyes and ears willing to see and hear. This also hugely explains the apparent snippets of ancient Asian culture that inspired the ten lost tribes of Israel enthusiams of the nineteenth century. Unfortunately our historians still resolutely ignore the mountains of evidence supporting the now massive Bronze Age Atlantean presence in North America and globally as well. Every where we find a pyramid, it says hello.
What we badly need to do is to uncover a library of documents. They were the inventors of the bronze alloy scroll so this is not even an utter impossibility. Certainly i have seen hints of such out there and we do have Joseph Smith's famous tale to reconsider. Divine translation assistance is also no longer taboo as i now know better on that. What i have read of the Book of Mormon does read as a local narrative of tribal woe neither unfamiliar nor particularly unique. Yet it is something that would be so recorded it that option existed.
However this is not about to happen unless every scholar get on side and digs up the evidence we already have collected. We have to accept that is is possible and that a thousand years is an awful long time for continuous activity that leads to an awful lot of intermarriage.
