Mankind’s belief in a higher power goes back since time immemorial. Prehistoric discoveries, such as rock paintings and archeological evidence found in burial sites, demonstrate that the human race already entertained a belief in life after death in the prehistoric age. According to anthropologists, humans used religion to understand the world around them. Forces of nature, diseases and other phenomena whose causes and origins could not be explained at the time were attributed to immaterial entities, as the human mind is prone to engage in a cause-and-effect understanding of reality and has a tendency to constantly strive to uncover the unknown.
