It is not really possible to talk about native american indians,because north and southamerica got populated from different atlanteen races from different directions.Some came from different parts of atlantis others came from the pacific.
Who was there first?all and noone.We all are coming from the"hood",from the northpole or rather the undestructable ground and populated later the compacting continents.
So much could be said;the so named american indians are all atlanteen source.Look Stanza X in the
"book of dyzan".Main authority from Blavatzkys "secret science":the first in each zone were mooncoloured,the second yellow like gold,the third red etc."The red" were the atlanteen anchestors from "the red" of today,that means the american indians.America or the americans got populated over million of years from different atlanteen races.But"the red" came from different parts of atlantis,what the same skincolour but the different physiological types of the american indian explains.While they are anyhow similar in the profile like you can see for example at the irokese,the sioux,the cherokee and of the south and middleamerican indians.
