So, I'm the resident Catholic apologist in my household and something that keeps my brother from the faith is that he sees the Old Testament as a politically biased history written by the Israelites/Jews to legitimize their conquest of Canaan.

His argument is regarding the Table of Nations found in Genesis. His argument consists of saying that the Bible got the historical fact wrong as the Canaanites as Sons of Ham aren't culturally separate from the Israelites who are Sons of Shem, even though the Midianites/Ishmaelites/Arabs also are Semites.

How would you respond to this?
