The world is designed with different types of creations; and human being is the best creation of Creator because of their proper knowledge of the separation between good and evil. All the creations are talented only for the benefit of the human. Before creating the human being the world was totally empty. After revolution, gradually different generation came and they created different eras. All the eras were not the equal with one another.
In the beginning of the world, the concept, thinking, nature and feeling of human being were full of dark and dull. They did not know how to lead a good and proper life. There was no touch of science, romanticism, socialism, ethics, philosophy, politics and religion. So, they did not feel any guilty to do any devil work; even killing another person. Their natures were totally violent like the wild animals. There was no fire, no cloth, no electricity and no missionary elements to be used. As a result their lives were driven under the blackest hole.
There was no presence of fire; so they hunted animals, birds, fishes and other wilders and took them alive or dead without cooking or burning. They stayed in the cave without building their houses. So, they had done wild like behavior with one another; i.e. sexual relation with many randomly, roaming. Actually they had no light of knowledge. Their lives were full of frustration and obscurity.
Even; there was no existence of culture and civilization. Oh; how ghastly the eras were! Can you ever imagine it! It means really unbelievable with the reality though it is real.
Changing is the rule of nature. So, all the things are not alike in all the time; and a moment do not stand forever. In a moment when they observed them these are not the real life and hope. For their own benefit and security they were bound to be unit and for their own happiness they started working to invent new things and elements. First they learned how to make fire from stone. Then they learnt to spin dress. Gradually they made a revolution of making brighter life and become a real human being and human nature had totally changed.
Regularly they have changed themselves from all the daily activities. There we find a huge revolution in the field of science, philosophy, economic, politics, socialism, criticism etc. So, the world becomes closer and human life becomes very easier and more comfortable. Actually, this revolution gives us peace but, chaise our humanity and kindness.
Do you ever think how harsh we are now! How strict our minds are! It’s totally unbelievable!
Only for a simple matter we kill other people without thinking about him; chase the honor of a virgin by raping her; i.e. even after raping she is being killed like a wild animal, with a simple issue we hide another people, kidnap, rob, social crash are very common at present. We become cruel like the ancient people. It’s human nature which is able to do anything and change the world in a moment. If it desires, the world will be intended like the paradise again if it misuse the gift, the world will be destroyed and be intended like the hell.
