The evangelical Protestants of the 19th century, considered the inventors of the term "Cradle of Humanity," made claims that the term originated in Mesopotamia in the 2nd century, and that it was used by early non-Christian Arabs, to refer to a geographic area that falls within a 1,000 mile radius of the spot they believed to be the birthplace of humankind. No documentation of such a historical use has been forthcoming. Nevertheless, the term has been used not only in religious, but also in secular contexts, and may therefore refer to different locations, depending on the views of the user.Creationist View
Jewish, Christian and Muslim creationists believe that man was created by God in a place called Eden and then placed in a garden located east of Eden. In the Christian Bible, Genesis 2:10-14 indicates the Garden of Eden was supplied by the Tigris and Euphrates rivers. Some early Christians (A.D second century) used the term to refer to a geographic area falling within a 1,000 mile radius of that location as the birthplace of mankind.
