The Unknown or Wrong Tomb Theory
As this theory goes, the disciples went to the wrong tomb, or did not know where the tomb was located.
This theory disregards the straightforward historical narrative about the events surrounding Jesus' burial and the post Resurrection scene. The Gospel's record indicates that Joseph of Arimathea took the body to his own private tomb and not a public mass burial ground.
According to the narrative, the body of Jesus was prepared for burial according to the burial customs of the Jews; the women sat opposite the tomb and watched. Not only did Joseph of Arimathea and the women know where the tomb was, so did the Romans and the Jews, because either both groups or one group placed a guard there. This theory is easily dismissed.
