Out of curiosity, if evidence for the existence of Jesus (let alone the resurrection) were so ironclad, how come early Christians had to go and insert forged accounts into Tacitus and Josephus? I have no problem with you believing whatever it is you'd like to believe, but please do not state that it is historical record, for it is not. It is simply faith.
Reputable Historians don't try to deny the truth of Jesus Christ's existence. You've been reading some Liberal crackpots rendition of History. Be careful who you choose to believe. Look into their other writings to test their fruits. They are going against all of recorded History to make these spurious claims.
So you are saying that evidence not acquired through the scientific method is invalid. Our justice system is based on evidenciary methods that fall outside of science. Is it completely invalid as well.
The world was forever turned upside down by the resurrection of Jesus Christ. Within one generation Christianity had spread throughout the majority of the Western world.
