Bones of Jesus & son uncovered in Jerusalem? Airing new evidence

A couple of these mysterious bone boxes are about to be unveiled in New York City, in good time to promote Cameron's latest made-for-television movie, which will be broadcast on Discovery Channel in the US, Channel 8 in Israel, and Channel 4 in Britain before Easter.

This is the guy that made the documentary with James Cameron: Simcha Jacobovici. He also did The Exodus Decoded which I saw. It was compelling. However, there was not a differing point of view in the piece. He provided his evidence without discussion. In the Exodus movie, he was incorrect on a biblical point. He says that the first born Egytpian males were killed in the tenth plague. First born ROYAL males, he says in the movie and defends that position by describing at length how the royal children slept in their beds on the floor, whereas the poor were on the rooftops and therefore avoided the killing gas. This gas fog is not without precedent and he continues to show how this happened in Africa.

But the Bible says otherwise (emphasis mine):

Exodus 12: 29-30 29And it came to pass, that at midnight the LORD smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle.

30And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for there was not a house where there was not one dead.

If he is wrong on this point, what else is incorrect?
