This sounds like a repetition of the thesis of a book called 'From Time Immemorial' by Joan Peters, which was popular on its release in part because it worked in service to justify what's happening in Palestine.
This was back in the 1980s, so the book was basically discredited by the time it reached UK reviewers and scholars. Then Defence Secretary Ian Gilmour pointed out that it essentially ignores Arab sources in his London Review of Books article. It was even dismissed by an Israeli historian as a "forgery".
A lot of the actual work in exposing the fraud was done by Norman Finkelstein, and this is just one of the reasons he's now unpopular in American intellectual circles (which are often quite firmly pro-Israel).
I personally haven't read the book nor the ample criticism, and have only heard of the argument through my study of Chomsky. He talks about it here in an excerpt from his book, 'Understanding Power': https://chomsky.info/power01/
