How do we know that we won't just cease to exist after that last breath? How can you tell for sure that consciousness does persist after your last breath? It could all just be wishful thinking. I would like to think that we do exist after death but I can’t just blindly believe it just because it’s a comforting thought.

Yes its true that you can’t create or destroy energy E=MC*C etc but that doesn’t mean that you can’t destroy consciousness.

Has anyone got any views that would put my mind at rest?
