I am not using the same argument. I am not arguing that something must be true by disproving something. I think you misundersand what I am suggesting here.

I am suggesting that there may be a legend that was somehow carried from the days that the Denisovians (ogress) mated with Homo Sapiens (monkey), so that that the modern-day Tibetans carried those genes for living in high altitudes. That mechanism for passing on those genes are exactly what the the article is suggesting.

At no point am I saying that these legends were somehow the cause. I am not sure how you got to that idea.
