The popular belief, based on genetics and archeological evidence, is that the Indians came to America from Asia when the North American continent was connected to the Eurasian continent through a land bridge (Berringia) exposed during the latest ice age some 11,000 to 26,000 year ago. It is believed Alaska and Canada were connected during the last ice age.
Archeological evidence suggests that humans lived in Brazil and Chile as early as 11,500 years ago, which means the migrants had passed over Berringia centuries earlier and gradually spread south on foot. (Until the white settlers came, the Native Indians had no horse or wheels for transport.) It is even possible that some of the early migrants came to America during an earlier ice age, 37,000 years ago, or even earlier.

That is an interesting thought, previous iceages, not one but many?
Imagine ice glaciers forming quickly and moving quickly across the landscape a sudden climate change, depleted ocean levels because all of that water would be on the surface of the land.
Now about the Continental drift, it seems that the continent Pangea divided, it would also be easy to conclude that the Earth was once much smaller. How then did the land bridge exist if the continents were once much farther apart? It is possible that humans migrated across a glacial pack or the continents drifted close enough together that the last couple of glacial ages allowed for this land bridge to be exposed.
It is also possible that if Pangea existed and the continents drifted apart, then the people could have always existed and the migration followed north into the glacial area.
This brings us back to how does the planet and life work together?

They are settlers of America before the English people came to America and too their lands.

It would be as relevent to ask not where did anyone race of humans come from but where did human life come from.
Critically thinking as I've tried to demonstrate above, it is possible that human life came from multiple sources at multiple times.
I think one of the things we have to explore are the movements of the plates, why do they move as they do?
What is the rate of movement, we know this is measured and what did the world once look like?
How much water is contained in the glacial packs and how much water would it take to cover the entire earth?
How much material could be pushed up out of the core of the Earth and how does the mantle float across the core, at what point do we all freeze?
As the crust of the Earth is cool and cooling, how long until we enter the final ice age?

They came from the area where present day Russia is. There used to be a land bridge during the ice age called the Bering land bridge. It connected the area where Alaska is today with the area where Russia is. More info can be found here: http://en.wikipedia.org/wiki/Bering_land_bridge
