There are two possibilities of identifying Mitsrayim: “Misr”=Egypt; or Mathura=Indus Valley. If Misr is not attested before 1300 BCE; and Mathura is attested from 2000 BCE or earlier then it is more likely that Mitsrayim was located in the Indus Valley.
Indus Valley is a possibility because many problems of the Exodus get resolved: The first Yam Suf could be the Indus River; the Sinai Volcano could be Taftan; the second Yam Suf could be the Shatt al-Arab. Then we have parallels between Adam and Swayambhu Manu, Noah and Vivaswat Manu; and Abraham and Rama. Hence it is possible that Adam-NOah-Abraham-Moses lived in Indus Valley and Moses led the Exodus from there. Thx.
