" In December of 2007 human bones including skulls, which have been radiocarbon dated back to between 1304 and 1424, were found in a museum in Concepción, Chile. These skulls were originally discovered on Isla Mocha, which is located 25 miles off the south-central coast of Chile. Since some of them have definite telltale signs of being Polynesian, the strong suggestion is that there was a pre-Columbian interaction between the local Mapuche people and the Polynesian seafarers. This contact is further supported by forensic evidence found near the Chilean site of “El Arenal,” which is a sandy dune approximately 3 miles inland from the coast.
Pottery found in Ecuador, predating the arrival of Columbus in America, have markings similar to pottery found on the southernmost island of Kyushu, Japan. Radiocarbon dating has determined the date of organics in the clay that survived the firing, or from food or liquids stored in the pottery, to be 4500 years old with a possible variance of 200 to 500 years, thus predating Columbus by a wide margin. There is no reason to doubt these findings, which indicate that Asians and Polynesians sailed to all parts of the Pacific Ocean, including the vast continents of North and South America that border it on its far eastern side.
It was always assumed that Spaniards introduced Chickens to the new continent; however the chicken bones found at the site also dated back to this era, proving that it was the Polynesians that first brought this edible bird with them!
The proof is conclusive…. America was discovered prior to Columbus! "
