Job himself and his family seemed to be agrarian and agrarians wouldnt normally need to deal with elephants/hippos and crocodiles.
I don’t buy it. Modern man’s arrogance causes us to sell those guys way short.
Think of the brain capacity of the first man created before corruption entered creation.
Couple that with a 900 year lifespan, and you’ve got some incredible potential.
Again, I would posit that without an imperative, no need would be seen to deal with such animals. So when they are encountered they would be seen as more fearsome than they need to be. The capability may have been there, but the imperative to exercise it, not yet there.
Basically, it may be we who have the mistaken arrogance that such conquest is naturally built into men, when it’s the “joy of the Lord” that brings it forth. And Job’s generation didn’t even have the Jewish revelation let alone the Christian one.
