I just don't see how people ignore a lot of evidence the predates the Bible possibly Judaism it's too many discrepancies to ignore not the Sumerians becoming a Mesopotamians was not the first Jewish person a Mesopotamian right so it kind of seems like he may have taken some liberties with the origin story this is how it seems from my perspective if you have any kind of evidence to refute this I'd appreciate it I am not trying to offend anyone I'm trying to understand what is what.

Moses was not the only one to marry out of the tribe. Joseph married an Egyptian woman, and (according to some opinions) his brothers married Canaanites. For that matter, what made Rachel, Leah or Rebecca more Jewish than anyone else?

The Jewish nation was formed at the event of Mount Sinai. Before that, they were descendants of a common father, Jacob, along with many who had come to join or had married into their families. Standing at Mount Sinai, they were chosen and appointed a “kingdom of priests and a holy nation.” They became a people Reply
