Question

What is the importance of Human life

Answer 1

The fact that we're humans is the main reason.  By valuing human life, we're valuing our own life and that of our loved ones.  We are promoting stability within our community by respecting the lives of our neighbors.  But you can see how subjective that is when it comes to wars and drone strikes, and even crime in other communities.  Human lives are destroyed needlessly all the time.  Other systems might simply value life as a whole, and believe in respecting an ecosystem, not harming any living thing without sufficient need.  Other systems value only "innocent" human life, which allows for and promotes the death penalty.  

The number of potential value systems is infinite.
