I was wondering where indians in the land called america how or from were they came from?

Question

Our histroy books tells us they were here first?Where did they come from?from adam&eve or where?

Answer 1

Best evidence of those living in the Americas prior to 1492 is that they originated in two different places.

Increasingly the evidence is that they first originated from Europe and arrived by boat (and maybe an ice bridge) settling on the East Coast.

The second Migration was likely by a land bridge between Asia and Alaska.

There is some small evidence of other possible migrations prior to 1492, for example, a small community of Welsh coming by boat to the Southern Americas and becoming the tribe of the Mandans.

Answer 2

New evidence is found quite often.
genetic evidence points to Northern Asia as the point of origin for Native Americans on the West Coast and Plains West of the Mississippi.
There is also some evidence of Northern European ancestry and Phoniecian ancestry for Native Americans East of the Allegenys.

A genetic study was done a few years back that showed that all Europeans and Asians (along with Native Americans) come from Central Asia, specifically Kazakastan.

Answer 3

A lot of evidence points to a human migration from asia across an area that is now under water in the Bering Straits between alaska and russia. There is other evidence though that suggests people might have arrived by boat earlier than that. Personally I think it is both.

Answer 4

The current theory is that there were three waves of immigration, either from across the Bering, or by boat from either the Polynesian islands or Africa (think of Thor Heyerdahl and Ra II, Kontiki).
