There was a pretty decent assertion that crossing the "Red" sea was really the "Reed" sea a while ago because the wind patterns can push back the water exposing dry land. But that, of course, illustrates that taking the Bible as literal history is a mistake in at least almost all cases.
Yep......... there's plenty of circumstantial evidence to support the Exodus narratives.
It was the Reed Sea, a vast water complex of papyrus marshes.
Only the slaves would have worked in or ventured in such infested places.
No self-respecting Egyptian would have considered or dared to venture into those places.
Only the slaves knew the 'wades' and channels.
Only the slaves knew the effects of the spring and neap tides.
Only the slaves could predict the tidal bores and Wind blown surges.
An HAT/LAT (Highest/Lowest astronomical tide, usually Spring and Autumn equinoctial) delivers a very low water at full ebb, with the fastest flood tide causing tidal bores in wide/narrowing estuaries, leading to very high tides.
A powerful South Easterly Storm, possibly over two days, could cause a Storm Surge on top of the HAT tide + a Massive flood and possibly even a water-wall like a tsunami can produce.
I wonder how geologically stable the lower Red Sea is?
Anyway, the time, the Full Moon, the local slave knowledge......... yep..... historically the Exodus is true, based up[on the balance of probabilities. No probs there.
