I was going to answer, "Yes I could survive without spirituality. That would be at the level of animals. Existing with no meaning and getting my basic needs for survival met." A hollow shell just feeding myself to continue with I know not what, but compelled to keep my physical self alive.
But then I remembered the burial rituals of elephants and realized that there is something deeply spiritual in that. I'm going to be thinking more about what evidences I see in the habits of the creatures.
