since science has no explanantion at all for concsiousness i am inclined to think that maybe it can live on. Everything about our
physcial bodies obviously dies, but the parts of us that make us who we are, our mind and our conscious experience, could, maybe, live on. I think this for a number of reasons. Mainly that Near death experiences all seem to be very similar, implying that there is some definite process that happens after death.
http://www.near-death.com/ is a good site if you want to weigh up what evidence there is for afterlife.
Most people think that great academics do not believe in such things, but when you look at a lot of their personal beliefs, a lot of them do. Einstein said: "Great spirits have always encountered opposition from mediocre minds." Einstein wrote favorably about psychic process on telepathy research in a preface he wrote of Upton Sinclair's book Mental radio. If its good enough for einstein to consider, its good enough for me.
Further evidence for this is that the strongest psychedelic known to man, DMT (the drug which gives us our dreams), is endogenous and has been hypothesised to be created in vast amount during death and birth. The effects of the drug are nearly identical to all NDE's. Shamans have used this drug to visit the 'spiritworld' and higher dimensions of conscious experience for millenium. Dr Rick Strassman has done a lot of research into this before he was stopped by various drug laws, but he did get a chance to publich a book on it, "DMT the spirit molecule", which has been acclaimed by a lot of top academics, read the reviews on amazon (

Can i prove life after death? no. But i do like to stay optomistic about it.
