Describe Humanity ( Base on Symposium, Bible Genesis, Bible Mark)

How to live? Life is no bed of roses; it can be perfectly smooth but being destroyed
completely in a twinkle of an eye. In this uncertain, miserable world, human being is so fragile.
So why human beings have to live in this world and continue suffering?
Different thinkers suggest different answers to this question, explaining the meaning of life and what aim human being should pursue in their limited life so that they can live a “good life”
