As the Bible says, the direct line of descendants from Noach through his son Shem leads to Terach the father of Avraham who is the father of Yitzchak who is the father of Yaakov (Yisrael - Israel). His twelve sons became the progenitors of the twelve tribes of Bnei Yisrael (Sons of Israel) or Israelites who became the nation of Israel at the Exodus from Egypt and the acceptance of the Torah at Mount Sinai.
Since Noah and his three sons are the only survivors of the flood, there is no need to go further back. Of course, the direct line from Adam through his son Shes to Noach is also given in the Torah.
Since this is directly written in the Torah, there is no need to point anywhere else.
