BTW, just over 5,000 years ago the Indians living near Oconto, Wisconsin smelted copper. They were first.

That is nonsense. Copper has been mined in the Old World for thousands of years, since prehistoric times. Some of the oldest copper-ore deposits of antiquity were in the Sinai, Syria, Afghanistan, Cyprus, Iberia and Central Europe.

That's right, they are thousands of years old ~ but the smelting of copper happened FIRST in Oconto, not in any of the places you named. And that, too, happened thousands and thousands of years ago.

Now, go back to sleep.

More to the point, they arrived at copper, and no got farther. The advanced metals were not mastered, pre-contact.
