Abraham, Isaac and Jacob are said to be the ancestors of Muslims, Christians and Jews. But the only one of these three that claims to be genetic is the Jews, who say for someone to be a Jew the mother has to be a Jew. (which is another strange thing) The other two religions are full of converts, there is no genetic element at all. Even among Jews there are converts, and there is also the theory that the present-day Jews aren't genetically related to the Jews in the Bible but are descendants of the Khazar people which converted to Judaism. This guy says in passing that Abraham, Isaac and Jacob are "forces of nature", so he seems to be implying that it isn't literal. The video doesn't even say Muslims, Christians and Jews, it talks about Islam, Christianity, Israel, Europe, Russia. What is the real meaning and where can I read about this?

But this is confusing because he says Abraham, Isaac and Jacob, but then he says Ishmael. Looking it up it seems Isaac and Ishmael are sons of Abraham and Jacob is son of Isaac, so it makes no sense anyway.
