Prior to the devastating eruption of Santorini, around 1500 BCE, (3517 years ago), Minoans, Phoenecians and Greeks had a great command of trade shipping and sailing. We all know these earlier civilisations were highly attunded to the movements of the stars, planets, and "gods." It is noteable that the repeating, 30-year celestial event descibed in Plutarch was actually found by evidence to have been real.
After the Santorini eruption, tsunami, and climate changes. Phoenecians and Minoans settled in Greece, Egypt, probably Palestine, and certainly in other lands far and wide. I believe it is probable that they influenced Polynesian and Micronesian shipping, and somehow affected places like Easter Island.
Ancient Egyptian mummies have been found with cocaine and coffee (and chocolate?) in their systems. These 'delicacies' are only indigenous to South and Central America, (possibly called the land of 'Punt'). The only way the royal Egyptians could have obtained these would have been from shippers, probably from Malta. Malta would later become the base of the Crusaders, (who later transformed into Masons), sporting their Maltese Cross.
Also note that recent LIDAR is revealing a treasure trove of many previously unknown ancient Mayan cities in Guatemala - a civilisation of as many as 10 million people. Since we Sapiens Sapiens all generated from the same families, and we try to maintain our contacts, in general, there is no way that a civilisation of this size could have been unknown to Malta, Egypt or Europe. There are ancient stone temples in Cambodia which are amazingly similar to temples in South America. And the whole pyramid thing is proving to have been so pervasive throughout the world, there is no way that it was not part of a shared, 'world society'.
There has long been association between France, Britain, Greece, Malta and the Middle East. As our human family expanded, simple and organised trade grew. Trade and shipping routes developed, as did wars to defend them. Some of the first trade items, going back tens of thousands of years, were beads (as 'money'), pottery, and possibly such animals as Dodo's and chickens. Ceramics were traded into the Middle East from China, (and Japan?), as early as 10,000 years ago - and probably earlier. One of the most beloved uses for pottery was as containers for wine, and beer, Since wine is a liquid, we don't have much evidence of it - but we do have some: Wine was a very big business in olden times, throughout the Mediterranean. Wine shipping and trading routse went from Greece to the Gaulis city of Vix, the wine capital of the world.
Recently the earliest known date for wine consumption has been pushed as far as 8,500 BCE, in Turkey. First Wine? Archaeologist Traces Drink to Stone Age. (2004 story). And, like ceramic pottery, wine also has early roots in China:
The earliest archaeological evidence of wine has been found at sites in China (c. 7000 BC), Georgia (c. 6000 BC), Iran (c. 5000 BC), Greece (c. 4500 BC), and Sicily (c. 4000 BC) The oldest evidence of wine production has been found in Armenia (c. 4100 BC),. - wiki: History of Wine
So, with all this going on - including the use of narcotics, and so on - you can bet there were trade routes and shipping. You had the beginnings of the Silk Road, and you had proto-Phoenecians running wine literally throughout the known world! And all of Eurasia was interconnected: Like, the mythology of pre-Vikings were connected to the Babylonian/Sumerian and Iranian religions of Baal and of Zoroastrianism, etc.
There is linguistic evidence of a relationship between Algonquin, (etc.), and Celtic languages. There is a Jewish genetic trait in some Cherokee. When Vikings got to Newfoundland, where the article above claims ancient Greeks had visitted to grow wine, what did they call the place? Vinland. Wineland! Remember, the climate in that area was not the same as it is today. But even NY state today grows grapes for great wine.
There have been certain interactions between North America and Europe after 9,000 years ago, when the ice-melt slowed, and the sea level stopped rising. But long before this, there was a lot of ice covering the North Atlantic, and much of Northern Europe. Ice-age type hunter-gatherers, and basic farmers, probably used long-established boats and ships to travel along the edge of the North Atlantic ice sheet, hunting seals - before there were even expansive currents available northwardly, due to the ice! So, over the centuries, as this ice receded, it would only be natural that sailors and shippers would vbery capable learn the new currents and winds that emerged! Therefore, by 56 AD, certainly the Greeks, well aware with the Solutrean legacies of Southern France, with the legends of Atlantis, could have very capably travelled the extensive route proposed in the article above, guided by currents and celestial bodies.
I am not saying that any one of the hypotheses mentioned here are known to be true. I am saying that they all fit together, especially in a model of human dispersement and evolution which is pan... word?.... not hierarchical but diffuse. The legend of Atlantis probably referred to great civilisation/s of North America prior to devastation by the commentary impacts of est. 12,800 years ago, and the vast fires and dust storms which followed. At that point, the main involvement of the Solutreans in North America would have vastly diminished. But, as I said, further involvements between the two continents did continue. See also:
