I missed most of the discussion, so I'm coming in with a very limited perspective, but I gathered that souls are a finite resource. There's a 'pool' they're drawn from and recycled into when things are born and die. 

However, what I'm not understanding is why this exists when we, as gods, can hocus-pocus things into existence. I understand we're not omnipotent, but we have the means to create. So why are souls so distinct?
