> But it is meaningless since they did not write about it The story of Leifur Eiríksson lived in the oral tradition and was eventually written down in Grænlendinga Saga around 250 years later (which is still another 250 years before Columbus). I bet that possible Polynesian contact would have lived in the oral tradition in a similar manner. Though way more time passed until the stories Polynesian were written down so I would expect them to be a bit more fantastical with the added time.
