That's quite a statement, considering the professor was not there.
It's like that old saying "All swans are white", but then they discovered black swans
in my country. You can't prove a negative. A good professor would say, "The Gospels
are set against an historic backdrop of Palestine 1st Century. We have no evidence
for some of the claims of the Gospels. They are mythic in nature but cannot be
disproven."
Re King David. Many, many, many atheists, skeptics and professors used to say that
"King David never existed." Until the evidence started emerging. Now they say "The
fact King David existed proves nothing." So they have shifted.
Ha, that's funny, no one in scholarship says that. Just like they don't say "Romulus is mythical in nature but cannot be disproven"
No one adds that tag onto myths because we know they are just stories.
Can you imagine how annoying it would be if every time a professor mentioned some ancient myth they had to say "but it can't be disproven"....
The professor doesn't need to be there, we have writings that are histories by bronze age historians and the gospels are not that. They are written entirely as myths were written. But going one better we have all the exact same mythology from many other cultures that pre-date the gospels. So Jesus is the Jewish version of the popular dying/rising in 3 days and erasing your personal sins and getting you into the afterlife savior messiah that every culture had in those times.
Thanks to Rome and later the Roman Catholic Church and tight control on information and influence people still believe ancient stories as if they are real to this day.
But like the professor pointed out literal translations didn't even start until the 19th century. The church did a good job of keeping peoples attention off the fact that the messiah story isn't even a Christian creation. Every time I see a apologist scholar debate a historian they strongly deny the pagan myth connection or say those myths came later. Then they are shown source materials from stone tablets or pyramid walls and can barely contain their shock.
The "god" of all gods was a minor Egyptian deity who bronze age people decided to focus their worship on. But the idea wasn't even original to Yahweh, it was stolen from an Egyptain "god above all other gods".
In the oldest biblical literature, Yahweh is a typical ancient Near Eastern "divine warrior", who leads the
heavenly army against Israel's enemies;
[8] he later became the main god of the
Kingdom of Israel (Samaria) and of
Judah,
[9] and over time the royal court and
temple promoted Yahweh as the god of the entire cosmos, possessing all the positive qualities previously attributed to the other gods and goddesses.
[10][11] By the end of the
Babylonian exile (6th century BCE), the very existence of foreign gods was denied, and Yahweh was proclaimed as the
creator of the cosmos and the
true god of all the world.
