Just consider how complex the human body is. Our bones aren't just pvc pipe, or our blood colored water. Take away one system and you cease to live.
But why debate, just realize that all of us are mortal. All religions are formed to try to satify the deep down need to "survive" after death. I only know of one that can. When a person earnestly seeks after God, he leads them to someone that can explain salvation to that soul. It happened to me, it can happen to you. I made fun of people "speaking in tougues", until it happened to me. Obey Acts 2:38, you won't be sorry.

Really? I'll be sure to tell the amputees, the blind, the deaf and the dumb.
