Now this find, if true, is ground shaking. Saint Paul said if the resurrection did not happen then Christianity is pointless. Islam believes in Jesus assent into heaven. So finding Jesus' tomb would damage or destroy about half the world's faith. But let us ignore that aspect and focus on the more scientific parts of the evidence.
The Jerusalem Post points out a few major flaws in the theory. The tomb is in Talpiot right outside of Jerusalem. Jesus was a Galilean, the Appalachia of its day (the city folk and rural Jews by Galilee tried to be as separate as possible), and had no ties to Jerusalem. There is no reason for him to have a tomb in city with no family ties to it. Secondly Jesus was not a rich man. Affording a tomb for himself, his family and extended family is not something the average carpenter could afford. Finally, while the tomb is for a "Jesus" and a few "Marys" one must remember that these names are as common as Maria and Jesús are today in Hispano countries. Think about how many Simons and Judases are in the Bible and you begin get the picture.
A weird claim by Cameron is that he is using DNA evidence to prove it is the tomb of Jesus of Nazareth. How? Is there the "God" Y Chromosome? All he can determine is if the people are related and that proves nothing. Hot Air has more on this.
So what is going on? It is simple. During the time of Lent religion is on the mind of many including the religious and non-religious. So now is the perfect time to cash in on causing religious controversy. National Geographic did this last year (same story too: an old find is given new life by hype). How things change how things stay the same.
