> [The Exodus] never happened. For decades now, most researchers have agreed that there is no evidence to suggest that the Exodus narrative reflects a specific historical event. Rather, it is an origin myth for the Jewish people that has been constructed, redacted, written and rewritten over centuries to include multiple layers of traditions, experiences and memories from a host of different sources and periods.

Those weren't Arabs.
