Let's get one thing straight: I am no one's "very own".
I'm willing to listen to Cameron's claims, but I'm highly skeptical of them. Atheists hold the gospel Jesus never existed, theists will hold that Jesus was resurrected and both camps will point out that a poor carpenter wouldn't warrant an elaborate tomb.
I don't see it as being all that radical a find. Apologists will ask "Were there bones in it?" and have appropriate propagandist answers for a yes or no answer... No will mean they'll stick with their story and yes will mean they'll have to get a little creative.
We also know from Josephus there were at least a half-dozen noteworthy Jews with the name "Yeshua" (Jesus) living around 2000 years ago. It could very easily have been one of them as Yeshua was a common name.
We'll see what tomorrow's press conference has to say.
