I tend to believe, at least for now, that there is no life after death. One thing that compels me to view the matter this way is what happens when trauma occurs to the brain. Various trauma, depending on which part of the brain affected, can alter the function of the person to such a degree that, in some instances (such as Alzheimer's disease) it seems as if it's not even the same person.
If we had some kind of Soul or Spirit that lives on, then wouldn't that somehow act to compensate for the lack of brain function? If brain trauma causes memory loss, why doesn't the Soul kick in and restore that function? The fact is that unless that part of the brain heals and begins to function again, the memories will likely not be retrieved. Clearly, even seemingly ethereal things such as memory are the result of chemical function of a physical entity - the brain.
