So you're saying that person who wasn't born until 4 years after this supposed Jesus' death has some first hand knowledge of his existence?
Another hearsay basically, but this is all tangential and not the point.
WOW. A whole 4 years!!! Yeah, no historian ever uses verbal accounts of others that lived in times prior to their existence. I guess we should burn all libraries then.
I guess I should throw out every history book I own because none of those authors lived during the times they describe. History through oral tradition. Did you ever hear of it? Why would Josephus works have any less relevancy than any other historian's work? His works are accepted by most historians, archealogists and helped in understanding the Dead Sea Scrolls.
If anything the fact that he lived close to Jesus' time should lend credence to what he wrote. He never stated that Jesus was God, he just stated that it was common knowledge at that time that such a man had existed.
