Where does one begin?

To give a very brief summary of the kind of thing you're asking about:

• The world was not created in 4,000 BC.
• There was no global flood in the 25th century BC.
• The world did not speak one language and all live in the city of Babel (Babylon) in the 23rd century BC.
• The biblical patriarchs (Abraham, Jacob, Moses, etc.) are folklore characters and probably did not exist, at least in the way they are depicted biblically.
• The biblical exodus of two million Hebrews from Egypt did not occur.
• The Israelites did not violently conquer the Canaanites. They were Canaanites.
• The kingdom of David and Solomon (if it even existed) was not a mighty empire stretching "from the Nile to the Euphrates".
• Jonah never converted Nineveh to Judaism.
• The book of Daniel gets the kings of Babylon and Persia wrong. In particular, there was no such person as Darius the Mede.
• Some of the historical details in the Gospels are implausible; there was no empire-wide census under Caesar Augustus as Luke claims, and the dead did not rise out of the graves and wander around Jerusalem as Matthew claims.

The real problem is treating the Bible as a history textbook, when it is more of a cultural artifact that includes poetry, mythology, folklore, fiction, allegory, satire, and so on. It is the modern reader who insists that holy books be literally true, not necessarily the ancient one.
