The last two centuries have seen a radical transformation in our understanding of Genesis 1-11. As a result, it is no longer possible to read these chapters as giving an accurate historical account of the creation of the universe and humanity and a reliable description of the earliest years of human history, contrary to what most Christians and Jews had previously believed over hundreds of years.
Firstly, and best known are the results of scientific discovery. Thus, it has been shown that the universe is not merely about 6,000 years old (or 7,000 years, if we follow the Greek Septuagint), as a literal reading of Genesis implies, but is actually billions of years old. Again, human beings were not uniquely created a mere few thousand years ago but are the result of many millennia of evolution from lower forms of life. Moreover, there is no geological evidence of a universal flood within historical time, such as Genesis 6-8 describes.
Secondly, Biblical criticism has shown that Genesis 1-11 is not the work of one man, Moses, as traditionally thought, but was written centuries later and consists of a composite narrative made up of two basic sources, commonly known as the Priestly source (P) and the non-Priestly source or Yahwist (J), which an editor has subsequently combined together, somewhat like a jigsaw. These sources do not always agree with each other, disagreeing, for example, over the order of creation and the details of the flood story.
Thirdly, archaeological discoveries of ancient texts in the Near East over the last two centuries have shed a flood of light on the background of Genesis 1-11. For example, it is now clear that the flood story in Genesis 6-8 is ultimately based on the Mesopotamian flood story, which is attested in three main versions: the Sumerian flood story, the Atrahasis epic, and the Gilgamesh epic (tablet 11). The biblical writers of Genesis have ‘monotheised’ and ‘ethicised’ this underlying Mesopotamian myth so as to make it compatible with Israel’s faith. Again, although the story of the multiplication of languages at the tower of Babel (Babylon) is clearly a myth, archaeology has shown that there actually was a massive tower or ziggurat at Babylon, made of brick and bitumen, just as Genesis 11 describes. Furthermore, the Garden of Eden story, in which humans gained wisdom but not immortality (in this world) and a serpent was involved in depriving humanity of this immortality, has precedents in Mesopotamian myths, whether or not Genesis is directly dependent on them.
However, I shall argue that Genesis 1-11 can still be seen as conveying profound theological truth as well as psychological truth about human nature, if we read its narratives not as history but as stories akin to parables.
