The history of religion is the written record of human religious feelings, thoughts, and ideas. This period of religious history begins with the invention of writing about 5,200 years ago (3200 BCE). The prehistory of religion involves the study of religious beliefs that existed prior to the advent of written records. One can also study comparative religious chronology through a timeline of religion, or the interrelationships and historical diversification of religious ideologies through the use of evolutionary philosophy and broad comparativism. Writing played a major role in standardizing religious texts regardless of time or location and making easier the memorization of prayers and divine rules.
The concept of "religion" was formed in the 16th and 17th centuries. Sacred texts like the Bible, the Quran, and others did not have a word or even a concept of religion in the original languages and neither did the people or the cultures in which these sacred texts were written.
