No human self survival instincts took over.
What human self survival instincts, dear TO (peace to you!)? After Abraham's trek from the East, Israel had pretty much always been taken care of, even when in Egypt. Even after leaving Egypt, they weren't starving. Heck, they had a huge number of animals with them (Exodus 12:3)! Could'a slaughtered and ate any one of those, if necessary. That wasn't the point, though...
The POINT... was that they apparently preferred to eat dishes as SLAVES... than wander as FREE persons, if doing so meant living on manna and water. But, hey, some people are meant to be slaves... always. Personally, like the crew of the "Nebuchadnezzar"... I would eat slop... if it meant being free...
The history of gods saving mankind in times of trouble have all been utter failures
There was no "time of trouble", here. Not for Israel, anyway. Israel had all it needed to survive. They just didn't like the... ummmm... "views" and inconvenience. What's interesting, though, is that the complaining didn't START with Israel - it started among those who went WITH Israel... and Israel just took up the whining WITH them...
Hence this makes it prudent for mankind to rely on himself for the sake of humanity's survival.
Perhaps. This was neither about humanity's survival OR Israel's. Israel's survival was never in question. Israel's faith... in the One who brought them OUT of Egypt, however... and His PROMISE to get them to where He said He would... and by what means... was. Still IS.
Human ignorance is the tragedy of humanity's perils.
It is. And lack of faith is often based on ignorance (i.e., lack of knowledge).
Again, peace to you!
