Animism means that you have a soul and spirit giving you life. There is a spiritual reality that goes beyond, and cannot be explained away by just physical, chemical, electrical processes of the body. There is a part of you that lives on after death, or consciousness can be separated from the brain and body. Skeptical people believe that the physical is all there is, everything can be explained in those terms. When you die it is eternal anesthesia, nothing more. Originally, in ancient times, people were animist, they believed in a non-corporeal soul and spirit. Unfortunately, we have never, and may never be able to absolutely prove that. I hope this helps, and I hope I got it right, research it to make sure. Animism may apply more to non-Christian shamanism, but do not quote me on that, I am not real sure about it.
