Within orthodox Christianity, a group of theologians, philosophers, and scientists have affirmed that Adam was created by God around 10,000 BC to 4000 BC. They are known as young-earth creationists. Within the category of young-earth creationists are two subsets: (1) chronogenealogical young-earth creationists who believe that the Bible does not allow for genealogical gaps in Genesis 5 and 11, thus establishing Adam's creation around 4000 BC and (2) non-chronogenealogical young-earth creationists who believe that the Bible allows for the possibility of genealogical gaps in Genesis 5 and 11 that would not violate hermeneutical rules, thus allowing for a creation date of Adam up to 10,000 BC. This article reveals how young-earth creationists have concluded this approximate age of Adam and to explain the reason for a 6,000 year range between both groups.
