Notice what the religious leaders do. They deny the facts and fabricate a story to cover the truth. They are like little children who don't like what they are hearing. They figure if they put their hands over their ears and make a lot of noise they can make the truth go away. Things haven't changed today.
People develop theories and fanciful explanations for the resurrection.
They try to make a lot of noise so they don't have to deal with the fearful reality of this historical event. Lots of people respond to the teaching of the resurrection with skepticism. It is an incredible story. God become man . . . giving Himself to death for sinful humanity . . . rising from the grave three days later. However the skepticism of the disciples gave way to the assurance that came from the evidence.
