I've begun to think about the idea that MOST of what we are as humans is invisible or spirit. Our thoughts, emotions, memories , ideas are what make us who we are. The physical body we inhabit seems to me to be a tool of sorts. So I'm leaning toward the idea of an immortal soul.
I've also talked with people recently who've had near death experiences and their stories are intriguing and the way they then approach life. It seems they have no fear of death and know that something better awaits.
Ultimately it's all unknown and a matter of faith and I'm sure there's good reason for that.
