There is an appalling lack of historical evidence backing the Bible's veracity

CS Lewis writes:Just as, on the factual side, a long preparation culminates in God’s becoming incarnate as Man, so, on the documentary side, the truth first appears in mythical form and then by a long process of condensing or focusing finally becomes incarnate as History. This involves the belief that Myth is ... a real though unfocused gleam of divine truth falling on human imagination. The Hebrews, like other peoples, had mythology: but as they were the chosen people so their mythology was the chosen mythology - the mythology chosen by God to be the vehicle of the earliest sacred truths, the first step in that process which ends in the New Testament where truth has become completely historical.

Webter's Dictionary on-line site writes: Myth
Noun
1. A traditional story accepted as history; serves to explain the world view of a people.
Date "myth" was first used in popular English literature: sometime before 1374. (references)Note: Myth \Myth\, noun. [Written also mythe.]. (references)Specialty Definition: Christian mythology
(From Wikipedia, the free Encyclopedia)A myth is a story with 'deep explanatory or symbolic significance', and Christian myth is therefore a story that explains or symbolises Christian beliefs.In theological and academic studies describing a story as myth does not imply falsehood. A true story can also be symbolic and explanatory. However in common usage a myth is a story that is not true. Describing Christian beliefs, such as Bible stories, as myth is therefore usually considered an attack on those beliefs.Many stories that do not come from sacred Christian texts and still do illustrate Christian themes, or are intended to foster Christian values, or address spiritual traditions. These stories are considered by some Christian journalists, theologians, and academics (see citations below) to constitute a body of Christian mythology. There are also stories which were once taken as true but are no longer accepted by most Chrstians, such as the tale of Saint George.
