From a Redditor:
[T]he components the make up “you” are broken down upon death and reused in other life forms.. thus causing parts of “you” to become worms, birds, snakes, etc. Thus rebirth.
…Buddhist doctrine of “anatta” which means “no-self” it states that there is/was never a single solitatary “YOU” that exists. It states that you are rather a multitude of things come together for a brief moment of time. A collection of things that decides to call itself “ME” and creates the illusion of the ego.
Under this understanding, “you” are a collection of billions of cells, or more precisely, trillions of chemicals, and even more precisely, quintillions of atoms….
So context is important here, “You” as in your identity, who you identify as.. dies permanently, because it was just an illusion, however your true nature (a massively complex configuration of the universe) does not die and instead takes upon new forms.
I like this view very much. Its very rational, enlighten and romantic to me, even if others may think of my impression as oxymoronic.
