Yin and Yang Truth Or Lie

Truth or fantasy, an ancient Chinese philosophy that opposite forces complement each other, my own philosophy is, without one the other does not exist. If evil were not present no one would know what good was and if good were to disappear no one would know what evil was. We live in a sinful world a physical world that none can be pure in heart or sinless our only escape from sin, is God. If sin were to disappear none would reach out to God they would have no reason to, if there were no death and only life in this physical world there would be no need to feed our physical body's to live. Each and every positive has a negative the world is made up in twos one complementing the other, right and left up and down, north and south, bad and good, boy and girl and so on. Without white back would not exist and vise a verses, we seem to forget why we exist at all, without life on earth we would never be able to know what death is, meaning: We would not exist Life complements Death so therefore, Yin and Yang are correct. Definition of: Yin and Yang In Ancient Chinese philosophy, yin and yang is a concept of dualism, describing how seemingly opposite or contrary forces may actually be complementary, interconnected, and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another.
