I'm not religious, but I'm open to the idea that there is something more than this, whatever this is. To me it doesn't seem logical that we would be born, live, die and then that's it. For what purpose? Plus, not that I've ever experienced anything supernatural, but I know people who have had ghost experiences, people I consider to be credible, and stories of spirits, ghosts, etc. go back thousands of years all over the world. Then you have the people with near death experiences, again, all over the world having similar experiences going back years.
I don't subscribe to "God" or any of the world's religions, but I think people who believe you simply cease to exist upon death aren't necessarily correct either. There is too much circumstantial evidence to flat out dismiss the possibility of some type of continued consciousness, whatever it may be.
