Wikipedia says on the Book of Exodus:
The story of the exodus is the founding myth of Israel, telling how the Israelites were delivered from slavery by Yahweh and therefore belong to him through the Mosaic covenant. The Book of Exodus is not historical narrative in any modern sense:modern history writing requires the critical evaluation of sources, and does not accept God as a cause of events, but in Exodus, everything is presented as the work of God, who appears frequently in person, and the historical setting is only very hazily sketched. The purpose of the book is not to record what really happened, but to reflect the historical experience of the exile community in Babylon and later Jerusalem, facing foreign captivity and the need to come to terms with their understanding of God."
Although mythical elements are not so prominent in Exodus as in Genesis, some writers claim ancient legends have an influence on the book’s content: for example, the story of the infant Moses’s salvation from the Nile may have some basis in an earlier legend of king Sargon, while the story of the parting of the Red Sea trades on Mesopotamian creation mythology. Similarly, the Covenant Code (the law code in Exodus 20:22–23:33) has some similarities in both content and structure with the Laws of Hammurabi. These influences serve to reinforce the conclusion that the Book of Exodus originated in the exiled Jewish community of 6th-century Babylon, but not all the sources are Mesopotamian: the story of Moses’s flight to Midian following the murder of the Egyptian overseer may draw on the Egyptian Story of Sinuhe."
Also, it says,
"The scholarly consensus is that the figure of Moses is legendary, and not historical. No Egyptian sources mention Moses or the events of Exodus-Deuteronomy, nor has any archaeological evidence been discovered in Egypt or the Sinai wilderness to support the story in which he is the central figure.The story of his discovery picks up a familiar motif in ancient Near Eastern mythological accounts of the ruler who rises from humble origins: Thus Sargon of Akkad’s Sumerian account of his origins runs;
‘My mother, the high priestess, conceived; in secret she bore me’
‘She set me in a basket of rushes, with bitumen she sealed my lid’
‘She cast me into the river which rose over me’.
The tradition of Moses as a lawgiver and culture hero of the Israelites may go back to the 7th-century BC sources of the Deuteronomist, which might conserve earlier traditions. Kenneth Kitchen, a solitary voice among British Egyptologists, argues that there is an historic core behind the Exodus, with Egyptian corvée labour exacted from Hebrews during the imperialist control exercised by the Egyptian Empire over Canaan from the time of the Thutmosides down to the revolt against Merneptah and Rameses III. William Albright believed in the essential historicity of the biblical tales of Moses and the Exodus, accepting however that the core narrative had been overlaid by legendary accretions. Biblical minimalists such as Philip R. Davies and Niels Peter Lemche regard all biblical books, and the stories of an Exodus, united monarchy, exile and return as fictions composed by a social elite in Yehud in the Persian period or even later, the purpose being to legitimize a return to indigenous roots."
What does the Church have to say about this? I know the Church does accept textual criticism, especially in regards to the Old Testament and the Torah, but is this going a little too far to say most of the Exodus was a myth and that Moses may have not even existed all all?
