The Initial Chronology in Genesis is clearly WRONG and contradicted by geological and astronomical evidence.

On the other hand, the story of Abraham and his descendants is confirmed by Archeology, Genetics, Geology, etc, so it appears to be basically TRUE.

From Google:
Rabbis and Jewish tradition view the Book of Genesis through a flexible lens that blends literal, allegorical, and mystical interpretations rather than enforcing rigid scientific literalism.
Diverse Approaches to Creation
• Non-Literal and Allegorical Tradition: Many classical and medieval rabbis—such as Maimonides (Rambam) and Nachmanides—interpreted the six days of creation metaphorically or as a framework for natural hierarchy rather than strict 24-hour periods. Maimonides famously suggested that God created everything in an instant, with the "six days" representing levels of being.
• Reconciliation with Science: Modern rabbis, including figures like Rabbi Jonathan Sacks and Rabbi Natan Slifkin, argue that Genesis functions as transcendent poetry or theological truth rather than a scientific textbook. Consequently, many mainstream rabbis comfortably embrace scientific findings like the Big Bang and evolution, seeing them as the unfolding mechanisms of divine will.
• Orthodox Literalism vs. Liberal Metaphor: While ultra-Orthodox and many Orthodox rabbis maintain a traditional belief in the historical and literal truth of the Torah's narratives (like Adam and Eve or the patriarchs), non-Orthodox movements (Conservative, Reform, and Reconstructionist) widely view Genesis as a sacred collective mythos, rich in moral instruction, cultural heritage, and metaphor.
Core Theological Focus
• The "Why" Over the "How": Rabbinic commentary focuses on humanity's role as moral stewards of creation (ki tov, or recognizing the potential for good) rather than the precise chronological timeline of physical origins.
• Truth as Story: Genesis is understood not as a recording of bare historical data, but as a foundational blueprint outlining the relationship between Creator, humanity, and ethics.
