Oh, so The Polynesian's discovered America, not Columbus?
I still say the vikings entered North America first. They came in through the Hudson Straight, into Hudsons Bay, down the Nelson, and down the Red river all the way to Mississippi.
They were our first "Indians". They adapted to the land, learned how to make tee-pee's and build canoes. Then they bred with the Mongoles who came in across through Russia followed the coast and moved east. THEN a few centuries later, Columbus came and discovered them. :o)
The Vikings found the "Indians" already here, referred to them as "skraelings". But check out Hjalmar Holand's book on the Kensington Runestone, if you haven't already.
No, Chuck Norris discovered America first.
