He isn’t self aware, and has little understanding of definitions, it’s why a discussion with him is futile for me, at least. He got his degree at a third rate school, most likely and hasn’t cracked a book on Biblical arecheogy since the 70’s if ever.
I'd say that it must have been a third rate school.
For example, at the very beginning, there are two Creation stories (Genesis 1 and Genesis 2), and in the story of the Great Flood, we can find several contradictions:
animals enter the Ark in couples (6.19-20, 7.9, 7.15) and in sevenfolds (7.2-3)
the waters of the Flood are from below the earth (7.10) and by rain (7.4, 7.12)
Noah and his family twice enter the Ark (7.13 and 7.7)
the Flood lasts one year (7.11 with 8.13); the Flood lasts forty days (7.17)
