Watch this video by David Wood. Volumes of evidence have been verified concerning the resurrection of Jesus Christ. The empty tomb is also very well attested even by the enemies of the disciples. If the disciples stole the body (as the ancient Jews held to) then this would never result in the conversion of Paul (an enemy of the church) and James (the skeptic unbelieving brother of Jesus). And why would the disciples knowingly suffer and die for something they know is a lie? This idea simply cannot account for all the facts. Christianity would have DIED if Jesus hadn’t rose from the dead and the first-hand witnesses met him and talked to him.
