In Einstein great equation E=Mc2, I believe there is proof of something after death in that famous equation. You are neither your body nor your brain; you are the electrical current running through your brain. Our brains allow us to store information, yet people live with damage brains. If our spark was to leave us, we would die. But that spark or current of electricity can never die, Einstein proved that energy can never die or disappear, but it can change forms! So if there is a after life, we would not retain our previous life’s memories. So our spark will continue till the "end of time" in some form or another. What do you think!
