A gentleman by the name of Lee Strobel in a book called "The Case for Christ" uses the question to try to disprove Christianity but ends up converting himself.  He was a atheist reporter at the time that he started.  He ends up running into various facts that have been run into before.  That there is books beside the Bible that mention Jesus, that we have more early copies of the Bible than any other book.  He also comes up with my support statements.  In short, he makes a pretty good legal case for Jesus being God and the Messiah.
