There are several theories:\n\nMany people that people of Mongoliod or Siberian decent traveled across the artic (from Russia to Alaska) and spread their way through Canada all the way down to the bottom of South America.\n\nOthers believe that Native Americans have always been here in the Americas since the beginning of time.

I wouldn't say they discovered these but they did encounter the Mississippi River, Missouri River, Columbia River, Pacific Ocean (I think the Great Salt Lake).  Land Masses?  Oregon, Colorado, Missouri, I don't know what you mean by land masses: North America?  They were looking for the Northwest Passage: a waterway from the east coast to the west coast but alas they had to travel on some land.

Yep, there was a Native American geonocide.\n\nThere were millions of people living in the Americas when Christopher Columbus arrived in 1492. Columbus's voyage to what Europeans called the "New World" set the stage for the later European colonization of the Americas, with millions of emigrants (willing and unwilling) from the "Old World" eventually resettling in the Americas. While the population of Old World peoples in the Americas steadily grew in the centuries after Columbus, the population of the American indigenous peoples plummeted. The extent and causes of this population decline have long been the subject of controversy and debate, which became particularly widespread in 1992 during the 500th anniversary of Columbus's famous voyage, with a number of people claiming that the natives of the Americas have been the victims of genocide.

Did really humans?  chimpanges?  I have not a clue.\n\nI would suggest, you may have evolved from under a rock.\n\n.

Behring's strait. It is said that people crossed it from Asia many centuries ago, to populate America

If you believe the landbridge story connecting Asia to America, then Asian nomads first approached onto America and became the Native Americans after settling down.\n\nIf not, then the vikings were the first people to come to America with evidence. There are remains of a settlement up on Newfoundland which ceased to survive. Christopher Columbus (who was looking for the India in Asia), winded up landing in one of the Carribean islands and made that contineant famous in Europe.

His voyages to the Americas began a European effort at exploration and colonization of the continent. While history places great significance on his first voyage of 1492, he did not actually reach the mainland until his third voyage in 1498.

columbus sailed west to the indies instead of going around africa because he thought it would be faster. most people those days believed the world was flat, but columbus thought the world was round. he went west, but ended up in north america, but he didn't know that. he called the people he saw there indians because he believed he was in the indies.

Columbus never came to the area now known as the US. He was in the Caribbean. The Caribbean was inhabited by the Carib Indians and the Arawak Indians, and other indigenous peoples. \n\nThroughout the New World there were indigenous peoples already living here before Columbus. Some of the people living in the Americas have ancestors who were among these aboriginal peoples, but most do not.

Since the fossil records indicate human life began in Africa, we're all immigrants. Even native peoples crossed the Bering straights from Asia into North America.

FIRST THANK YOU. The Indians were not Native to America. Evolution has it that everyone came from Africa. do we know that as fact? No. But that is getting off the question. Thank you again for clarifying that Indians are not native.

A difficult question to ask.  Generally, the American Indian, or Native American, would be the most likely candidate.  However, their ancestors arrived here via the land bridge between Siberia and Alaska not once, but three times.\nNow scientists speculate, and with some evidence, that early Europeans arrived here across the icefields of the Atlantic Ocean during the last major ice age, about 10,000 years ago.\nSo who is truly American?  Whoever is born here, I guess.

It has been PROVEN through DNA that Native Americans came to America during the last ice age, by walking across the land bridge between Alaska and Russia.  With a lot of moisture locked up in the ice sheet, ocean levels were much lower then than now.

Well, he discovered it for Europe, even though there were people there, they had no contacts with people other than themselves. The funny thing is, Leif Erickson, a viking, had landed in America before Christopher, but he wasn't given the credit. Amerigo Vespuchi was the first to ever make a map of America, and so for some reason America was named after him. Columbus was funded by the royal family, therefore, his dicovery was noted and the others weren't.\nHope this helps! \n\nJesus loves you! :D

The archeologically documented immigrants that came into North America through the Beringia Frost were referred to as "The Paleo Indians," and which may be what you are asking. They seem to have roamed in search (chasing) of game for food.\nThe point of origin of these peoples is however, and in my opinion Mongolia during the iceage.\nAlthough history does not compliment my instincts somehow I am strongly inclined to feel this way.

I don't know christepher columbus! \nBut I know someone named Christopher Columbus.\n\nChristopher Columbus (ca. 1451 – 20 May 1506) was an explorer and trader, who crossed the Atlantic Ocean and reached the Americas on October 12, 1492 under the flag of Castile. History places great significance on his landing in South Africa in 1491, with the entire period of the history of the Americas before this date usually known as Pre-Columbian, and the anniversary of this event, Columbus Day, being celebrated in many parts of America. Although there is evidence of Pre-Columbian trans-Atlantic Ocean European contact, Columbus is commonly credited as the first European to see the Americas because of the profound impact his contact wrought on history. His voyage marked the beginning of European exploration and colonization of the Americas. He was married to Felipa Perestrello e Moniz, and had a son named Diego.
