pyramids predate Abraham, so I doubt it.
The “hebiru” were part of the workforce impounded to build the cities of Pitom and Ramses. Lots of labor unrest at that time, and apparantly some of them absconded.
since these cities are in the north, where it is swampy, evidence may never be found. Mudbrick doesn’t last long in watery areas...
But 600 thousand? I doubt it.
The best explanation of the exodus was when some military guys examined the evidence and explained how a good general would use flame and smoke to guide people and also to fool the pharoah’s army to wander into a tidal flat, where their wheels would get stuck when the tide came in...
The Giza pyramids predate Abraham. In the Bible there is a figure of 400+ years from Abraham to the exodus, and then another 400+ years from exodus to David. That would put exodus earlier than Ramases II and later than the Hyksus and Thera. In -1500 +/-50 years there was a major eruption of Mt. Etna whose ash cloud I think could have caused many of the “plagues” listed. Since strong volcanoe periods tend to have events in more than one place, and since western Saudi Arabia has considerable evidence of volcanic/magmatic activity, my theory is that the pillar of smoke by day and fire by night was volcanic. Underground magma could have caused “inflation” of the land, which with a good strong wind could have created a temporary land bridge. At any rate I think the Exodus was an 18th dynasty event and probably at or right after the time of Hatshepsut, who definitely was several centuries too early to have been involved with David.
