Crazyguy,
Broadly speaking, I have no dramas with your general direction. Of course, each of us will disagree on details, but then we are not clones of one another.
By disagreeing, we sharpen our own thinking, learn from others, and constantly grow. To demand that others must agree with us would make us candidates for membership of the Governing Body.
None of the Scriptures represents what we would term "history". They are not literal accounts, including the Gospels. The are religious accounts that are driven by ideology.
In my view, the OT and the NT are vehicles that use superstition and the supernatural to manage and control. It is only by reading and researching the full contexts that we can understand and be able to withstand the pressures employed to control us. To me, one context is that the NT is as much a Jewish product as is the OT, which helps us better appreciate it.
I do not know the extent of the Egyptian control. Moses' Yahwist religion came from down south, from the Kenites while at the latter stages of both Israel's and Judah's history, they were dominated by Assyria. Judah was the minor party in the relationship with Israel, despite the propaganda from Judah.
