Under monotheism, existence is seen as linear-from beginning to end in a straight line. In East Asian belief, it is a cycle-death and rebirth.
Both are correct.
All life with a qi goes through the cycle of death and rebirth as they incarnate again and again to learn the lessons they are meant to learn in this plane of existence. Meanwhile, on a cosmic level, the Sun will eventually burn out, as do all stars, and the Universe will one day cease to exist. Cyclical on a “micro” level, linear on a “macro” level. Think of a wagon where the wheels go around and around yet the wagon itself is propelled forward. The individual wheel is in a cycle, yet the wagon itself goes from one place to another.
Also, a common monotheist misperception is that “every life is valuable”. This is false, but a “qualified false”. Life by itself has zero value. The only value a single life has is how it interacts with other lives. Given the interconnectedness of all lives, the ultimate value of a single life is based on positive or negative, good or evil, interaction with other lives both on a macro and a micro level. Each human has a choice whether to interact with the world in a good way or an evil way. The Law of Three governs the interactions of all lives.
