If you mean abiogenesis (or whatever the 'first cause') I can tell you that the reason I don't 'touch' it is because I don't find it of any great practical importance. Evolution is profoundly crucial to the advancement of modern science and the improvement of humanity; the initial origin of life borders on a metaphysical question of little relevancy at least at this juncture.
From a practical standpoint, defining the origin of life may have some tangential importance in terms of theology, but either possible answer really tells you very little of value in the grand scheme of things (though many would pretend it does). The practical elements of theology may far more readily be addressed in other contexts, assuming that's the desired inquiry.
BTW, the biomass does not merely get 'recycled' from some original reservoir established at the dawn of life. If that's what you're implying, then that's a ridiculous statement. The organic biomass is continually being synthesized at various base levels of the ecological hierarchy.
Where can I learn about this???
