I think a lot of the skepticism regarding life after death comes from the connection in many people's mind between religion and a belief in an afterlife. But there is no necessary connection between the two. It may well be that death is simply one more phase in an ongoing adventure of being. In fact, one could argue that religion has exploited the continuation of existence in order to exercise control over adherents. I happen to think that life does continue in some way, shape or form, mostly because of some experiences I've had. I also think that worship of God should focus more on simple gratitude for being in the first place.
