The idea that “you” persist after death does not hold up to the current understanding of memory and identity. There is no evidence that human consciousness persists after death. Some believe that technology could someday enable humans to resurrect consciousness after the death of the body.

The idea of reincarnation challenges many fundamental concepts in neuroscience and biology. For instance, it’s not clear how memories could be transferred from one life to another after the death and decomposition of the brain, which is currently understood to be the organ responsible for memory.
