To sum it up down to the basic primitives, there are ones who need to practice a religion and/or believe in a higher power for them to go through their life, and there are those of us who do not need to practice a relgion nor believe in a higher power for us to get through our lives. The levels of practice of a religion and beliefs in a higher power vary based on the questions the person needs to be answered.
If that's not able to answer your question, gcn_zelda, I'm not sure what will. It correctly and directly answers the reason for certain people not needing or wanting to practice a relgion nor believe in a higher power.
