Is there life after death?

Is there a soul? Apparently there is evidence of a soul. There are many cases where patients being operated on and was flat lined (meaning that the hart had stopped and was clinically dead) has left their bodies and was viewing the operation being taken place on their own bodies from above. They saw everything and heard everything and it was verified by the doctors and nurses. Many has claimed to have met deceased relatives and even met with God before returning to their bodies. Is this proof of an afterlife? What do you think?
