Thank you for your question. I've heard you ask many witnesses this precise question, and you've had a lot of different kinds of responses.
For me, the crux of your question relates to the fact that you seek to create.... It sounds as though what you are trying to find is a way of legitimizing or confirming knowledge from different systems. I think this is fundamentally impossible, which is why you've received so many different responses.
As I said earlier, it's very difficult to say I can confirm something is true in a system about which I have no understanding. My example earlier was this: If I sit down with a scientist and ask them to explain a complex scientific concept to me over a period of three days, or even three workshops, I don't think I could walk away from that saying I had verified that this complex scientific concept was indeed true from my own indigenous perspective. Similarly, I think on the flip side that it's pretty well impossible for non-indigenous systems to try to somehow verify or confirm the veracity of indigenous knowledge systems.
We can see that the courts in Canada have also struggled with this. We have some sort of challenging test the courts have laid out—10-part tests around how you define something that is central to your indigenous identity, for example. All of these tests have, for the most part and for many years, relied upon social science evidence, for example, like finding some kind of non-indigenous study to confirm it.
