It is in vogue these days among conspiracy theorists to suggest that the indigenous population of the Americas are relatively recent newcomers; some have suggested they are one of the lost tribes of Israel, others have suggested they came from Ancient Egypt, Atlantis, Imperial China, are Basques, or even extraterrestrial colonizers. Matlock thinks they're from India, and he has proof such as the fact that a few O'odham words sound a little bit like some Sanskrit words that don't even mean the same thing. Well, I can do that too: The O'odham word "Waw Giwulk", when pronounced, sounds a little bit like "Wow! Key works!". The English word "diarrhea" is clearly composed of the Japanese roots "dai geri ya", meaning "it is a big diarrhea". See? Anyone can do it for any two languages.
