This book has been written with the premise that we should refresh our views about existence of God because most of the beliefs on God had emerged during the period when people did not even know whether the sun revolves around the earth or the earth around the sun. They even believed that some demon may be devouring the sun during the solar eclipse and the moon during the lunar eclipse while today even a school going child knows that the sun and the moon appear to disappear only when either moon hides the view of sun or the shadow of earth falls on the moon. The book gives sufficient food to think, "God may not come down from the heavens to convince us whether He exists or not. So we have to find out ourselves only whether He exists or not."
