WHO WAS JESUS‪?‬

Writing about Jesus makes me sad, but I have a lot of unanswered questions. I was watching the reconstruction of the real Tomb of Jesus Christ, which didn’t answer my questions, but only brought more questions upon me. See they unsealed his tomb for the first time in over 500 years or something, and they found a tunnel from the Tomb leading out of Jerusalem. Ok, here’s question number 1. What was that underground tunnel used for, and why was a 20ft drop to that tunnel discovered under Christ’s tomb?
