Professor Robert Winston presents a definitive three-part documentary series on the history of mankind's quest to understand the nature of God.
The Story of God is an epic journey across continents, cultures and eras exploring religious beliefs from their earliest incarnations, through the development of today's major world faiths and the status of religious faith in a scientific age.
The series examines the roots of religious beliefs in prehistoric societies and the different ways in which humanity's sense of the divine developed. It looks at the divergence between religions that worship a range of deities and those that represent strict monotheism.
The series begins with Professor Winston examining the religions which believe in many different gods and explores why mankind started to believe in God at all.
The answer to that question, says Professor Winston, can be found in the caves where our ancestors first approached their gods and in the fields where people still call on them for help, in the cities where our ancestors have been honoured and in the temples where the gods have been appeased with sacrifices.
"But most of all the answer," says Professor Winston, "lies in the human desire to be united with something bigger than ourselves."
