Wow, another debate which has skewed towards a flame of religion, atleast I'm not responcible for this one. The Bible can be used to justify almost any argument, but if you look up existentialism you can see there is more to the Bible than meets the "stubborn" eye. I wouldn't keep poping-up if people would just keep an open mind to one of the two only non-manmade religions.
As for the life after death debate, I believe that the energy in our bodies reunites with the infinite universal energy which we come from as we enter reality. Iban brought up a good point in terms of Metaphysical Subjectivism. Reality is just what we percieve it to be, and many people have been able to rise above it. Also, everything I have experienced in reality (mostly in terms of the 5 senses) I have also experienced in my dreams. So, reality is just a sophisticated dream, and I think the afterlife is the real reality. But, that's just my two cents.
