Human beings can’t be enemies to each other. They have naturally evolved to live in coexistence. The ideas of rivalry, hate, and enmity came into human imagination when false beliefs were formed in the absence of complete knowledge of life and nature. Human beings used their beliefs to navigate through life. With time, they shunned some false beliefs, while retaining others. However, until the dawn of the all-inclusive and absolute knowledge of coexistentialism, the knowledge that human beings had, largely remained a guesswork-with so many missing links. Now, with the coming of the complete and practicable philosophy of coexistence, it can be verified that all human beings are by nature good and righteous. In their real nature (that is ever free from false beliefs), no human being wants to hurt or defeat the other human beings for his own good.
