I liked the story. It's not what I call "officially accurate" but you can find ideas in it that ring true to most all other religions. Every religion has something true to it and this video explained at minimal concepts that basically identify the "trinities" or "family characters". It may have seemed racist but the truth is history does need "genetic differences" for story telling purposes.
All I would add is that the "indians" possibly had slanted/olive shaped eyes and thus we have the usual caucasian/asian/black trio that most bioorganism groupings seem to construct down into eventually. I found this at very least interesting.
