Unfortunately the reality is even sillier.
Buz's source claims that some of the Stele text is "identical" to parts of the Bible. It isn't true but Buz can't admit that his source is saying something that isn't true. So even though the guy is trying to claim that the Stele contains parts of the Exodus story, Buz goes looking elsewhere and picks on the Flood myth because it looks more like the storm than the supposedly "identical" Exodus.
What makes it even funnier is that Buz is trying to defend a source that argues that Exodus is a distorted version of the real events.
And funnier still is the fact that elsewhere the guy one-ups the Da Vinci code nonsense by not only claiming that Jesus married Mary Magdalene, but that they were brother and sister too !
