We’re not “searching” for mystical reasons. This isn’t like how scientists used to attribute unexplained phenomena through metaphysics, which they abandoned once they found a viable scientific reason.
In hashkofa, the metaphysical isn’t an attempt at explaining something unknown; it’s a reality which doesn’t preclude physical earthly reasons. When chazal say that there’s a malaach underneath each blade of grass telling it to grow, that was not said because they struggled to understand why the grass grows and a malaach making it happen solved the conundrum. Rather, they were saying what’s going on behind the scenes, on the higher planes that exist above the physical world. The physical world, termed “olan ha’asiah” is the last rung in a domino effect sequence that starts on most high in shomayim… however ultimately what’s decided in shomayim is due to our actions (asiah) down here – that’s why yaakov saw the malachim “olim veyordim bo”, first rising from earth and then going back down to it from shomayim.
It could be I’m reading a lot into what you’re saying, but i think it’s worthwhile to explain this distinction nonetheless.
Anyways, the reasons given augment our understanding of history
