Easter Island is basically half way to South America. If they can make it there there's no reason they can't make it to Peru or Chile.
Easter Island is the most isolated island in the world. Add to this that there are lots of islands to its west, and few to its east, and it is a logical stopping point.
Well, isn't Easter Island kind of the New World anyways?
No, it's firmly in Polynesia.
But I can see how they got there and stopped. The expeditions weren't coming from a centralized location like with later European empires, each new island was colonized by the residents of the last. And having gotten to Easter Island they were unable to sustain the levels of technology that they needed in order to move on to South America, not for very long.
They deterioriated a lot over time, but they had a few centuries of high technology. More against them is the notion that they would bother to make the journey. Population pressures were never particularly high on Easter Island for most of its history, and when they were, the civilization simply collapsed.
I suppose one could make a stretch and say that the word "Aztlan" existed 4-5 thousand years ago, and "Aztlan", or some variation of it, was mis-spelled/corrupted into "Atlan", and given the Greek "tis/tos" ending. (Atlantos/Atlantis)... Of course, that's a long shot.
An extremely long shot. No ships of the ancient world were equipped for consistent trans-Atlantic voyages. Sure, Thor Hyerdahl managed to do it. He also had the benefit of knowing for sure where he was going, and going to and from a modern civilization. The idea that people crossed the Atlantic and left no record except for some "Atlantis"-"Aztlan" connection is ridiculous--especially given that the Aztecs rose to prominence millennia after this legend came about in the Old World.
This has been belived for sometime as it is because there has been sweet potatoes in polyensia since the 1300(ish) and it is a new world crop...whilst all the other crops appear to be from southeast asia .
There are also African yams, which was much more widely known in Polynesia.
How about hunter-gather Asians migrating over the Bering Strait, wouldn't they have been first? Yeah, I went there.
Or sailing down the coastline.
Um, anyway, more interesting ideas about other cultures reaching the Americas before Europe: Those big Olmec heads are said to resemble Caucasion and Negroid faces,
They don't. Bone analyses of Olmecs show that they're simply stylized versions of the local's faces.
which leads people believe that perhaps Phoenicans made it there,
Which is preposterous. They did not have the oceanfaring technology to do so, and if they had, they most likely would have written down their journeys somewhere.
also, I read some early explorers found a colony of black people there,
Which is probably about as credible as the El Dorado myth.
and at some point I heard that Mali may have known something about the Americas.
The Malians were not great seafarers, and if they did know about it, it is strange that their greatest wanderer, Ibn Battuta, never even bothered to head that way.
Finally, apparantly Roman coins have been found in South America, true?
Which can be easily explained by hoaxers or random shipwrecks. The Romans, meticulous record keepers, NEVER mentioned the Americas.
The likelihood of consistent pre-Columbian contact is very near zero. If there had been any kind of contact, then the massive exchange of organisms which did occur (the Columbian Exchange) should be in evidence long before it actually was. Why is it so hard to accept that Columbus was the first one who really opened up the Americas?
