Who, When, and Where Wrote the Book of Genesis?

  Who, When, and Where Wrote the Book of Genesis?  A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN     CONTENT [i]   Abstract [ii]   Introduction [iii]   Egyptian physician [iv]   Asian diviner [v]   Conclusion [vi]   References [vii]   Application [i]   Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research. [ii]   Introduction According to Rabbinic Judais...
