Of course, Life goes on after death....even for those who think otherwise!!
We get reincarnated into other bodies and develop further...and when we are sufficiently developed, we become Free and stop reincarnating. That is real Freedom.....freedom from the sense of individuality that makes us self obsessed.
The entire Hindu, Jain and Buddhist philosophies are centered around this concept.
What evidence do we have? There are thousands of NDE's that indicate a life after death. Ian Stevenson has done significant research on reincarnation and found some evidence.
It also makes more sense than the 'food for bacteria' theory.....and ties in with our general tendency to become more and more loving, selfless and universal.
Near-death experiences prove nothing, because they are
near-death experiences. If the person had actually died, they wouldn't be around to talk about it. I know we say things like "she died three times on the operating table", but that's loose language, meaning that her heart stopped three times, which used to be the definition of death, but is no longer adequate, now that hearts can be re-started.
