In the Monte Verde site, there were also several human footprints and remains of ancient tent poles. They also found seaweed which seemed like somebody or someone chewed it. But Monte Verde was 8,000 miles away from Triquet Island then how come human evidence was found in this place too? With the help of carbon dating technology, the results showed the scientists that this evidence was around 18,500 years old or you could say the oldest artifacts ever been found in America.
