There appeared the definition that restriction of knowledge is seen as one of the major reasons resulting in long- lasting existence of religion as an obstacle for the development of scientific knowledge. Limitations of knowledge related to natural and social phenomena drove people to believe in existence of mystical forces directing all things. For a long time humankind depended on sacred forces to explain all ins and outs of living things. Currently thanks to quick development of science and bright achievements in a quantity of fields laws of the world have been discovered the phenomena considered as mystical have become self-evident and explicit. It is thought that it is the reason for the end of belief and religion however historical reality proved the opposite. Religion not only remains existence but also develops quickly together with the development of human civilization.
