The film makers were on the Today Show this morning. They kept saying they are only documenting, not making any claims.
Their Exodus Decoded had a steady stream of claims, special pleading built upon conjecture and conjecture built upon error. I would say that the "claims" were the very glue keeping the whole thing together. They "documented" a Mycenaean tombstone that has absolutely no connection at all with the biblical exodus; it was the "claim" (pulled out of thin air) that Israelites must have escaped to Crete that made the connection. They documented the killer lake Nyos in Cameroon, Africa, which had a deadly limnic eruption and carbon dioxide leak in the 1980s, but again that has nothing to do with the exodus; it is the "claim" that a similar mechanism was involved in the Tenth Plague that made this relevant, never mind the fact that the Nile is a running river, not a lake, and never mind the fact that it lacks all the geological features that made the Nyos lake lethal. They documented the Serabit el-Khadim turquoise mine in Sinai, but this only has relevance through the "claim" that Israelites were the slaves used for labor there. Too bad that the site dates several hundreds of years before Jacobovici's date for the exodus. And which date is that? Jacobovici lumps together events separated from each by decades if not centuries (the Hyksos expulsion, the eruption of Santorini, the Ahmose stele), fills in the gaps with conjecture, and then five minutes later takes the conjecture as established facts on which he builds further conjectures.
They've already claimed that this tomb is indeed the Jesus family tomb. Looks like we are in store for more of the same from Jacobovici.
