If you see video of these people in India, it would be incredibly obvious that they were Jews. Even though they look like all the other Indians, they are carrying on practices that are all traditionally from Judaism and yet they don't know how they got to where they are and nobody around them does anything remotely similar to them religiously or culturally. There are a few of these tribes found around the world and its kinda freaky looking.

I have seen that video.
I think it was on the History Channel.
(additionally I was given a copy of it by my daughter for Christmas! She knows about my fascination with archeology and the classical world.)
I don't think physical looks constitute any sort of proof!
I still don't think enough is known about 8th century BC Judaic ritual practices to use that as proof either.
The Y-chromosome test would be the strongest proof.
