Why atheism? Is it good or bad?

From the dawn of the history of mankind, faith in God too originated. Man strongly believed in God as he had to face too many hardships for his survival. He required an inner power to support him in every thing he did. He started worshipping nature and developed several ceremonies and customs as an integral part of his faith.
As everything has two dimensions by the passage of time gradually man turned against god. He believed that human beings are the real rulers of earth. He began to believe in himself which resulted in the theory of atheism .an atheist never believed in god. An atheist always questions the power of God. An atheist gives prominence to scientific theories and principles. To him God is an imaginary creation of man to exploit his fellow beings. They question the existence of god by put forth the question that if a supreme being exists the world would have been a better place to live without any calamities or disasters. Prayers are waste of time as it does not prevent any of this chaos. According to them the human beings has responsibility to life and they have every right to enjoy all good things in life. They believe that only hard work makes a human being successful in life.  Morality, life after death and religious beliefs are irrational and mislead the mankind.
In the modern era were technological developments are so advanced many people tend to believe in atheism. For them self confidence, financial security and other material possessions are the prime concern. To some extent atheism helps people to have a faith in themselves to face any crisis in the life.
The other perspective of atheism is even though there is rational thinking one should before being an atheist should think that even before the origin of this concept world existed. Even though there are theories relating to the origin of the world like big bang theory no body have the correct answer to this question. At this point the relevancy of religious books should be taken seriously. All religions in the world firmly state that the world and human beings are the wonderful creation of the almighty. The origin of life and its existence is the true gift from god. No atheist had ever given a satisfactory definition to the life. It is evident that true trust in the power of almighty can never be taken aback with atheist concepts.
