Archeological evidence for Jesus?

AP reports:

A burial box that was recently discovered in Israel and dates to the first century could be the oldest archaeological link to Jesus Christ, according to a French scholar whose findings were published Monday. An inscription in the Aramaic language — “James, son of Joseph, brother of Jesus” — appears on an empty ossuary, a limestone burial box for bones….
Until now, the oldest surviving artifact that mentions Jesus is a fragment of chapter 18 in John’s Gospel from a manuscript dated around A.D. 125. It was discovered in Egypt in 1920.
