They presumably asked for a source for both claims, your only provided one says you lived among them. Either you grew up among both populations or have provided no source for one of your claims.
I still have no idea if you grew up among Aboriginals or Native Americans, or what makes you so confident about the other race/culture's beliefs.
Context makes it clear which claim they were asking for.
In any case, I'm not providing a source. This is a somewhat commonly known thing, and I was speaking from personal experience. If you're still really unsure where I grew up, you can probably figure it out from my other comments.
Feel free to search for whatever you find sufficient to corroborate my claims, or continue to be skeptical (as you should). I don't mind either way.
Which makes you Speaker for the Religuous Beliefs of the Bulk of Aboriginal Australians?
Yeah, right .. just keep digiging that hole deeper Kartiya.
Where did you grow up that simultaneously had a large Aboriginals and Native American population?
