Very Interesting Lee, thank you.
I ran across a web-site quite some time ago, where a serious comparison was being made of Hopi indian terms, and India indian terms.
The Hopis also have something like an "Om" symbol. It was enough to convince me, but I have no idea the website, it was so long ago.
I believe they ( Hopis ) were supposed to have traveled all the way South America too, according to legend, ( or perhaps their forerunners - the mysterious 'Anastazi'(sp?) ).
