But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead? If there is no resurrection of the dead, then not even Christ has been raised. And if Christ has not been raised, our preaching is useless and so is your faith. More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. For if the dead are not raised, then Christ has not been raised either. And if Christ has not been raised, your faith is futile; you are still in your sins. Then those also who have fallen asleep in Christ are lost. If only for this life we have hope in Christ, we are of all people most to be pitied. 1 Corinthians 15:13-19

            Although unlikely it could ever be disproven, if it were discovered that Jesus never rose from the grave then our faith, according to Paul, would be futile.  The resurrection proves that Jesus is God and that he’s a man of truth, correctly predicting the future and having power over death.  If Jesus were still dead, his bones in a tomb, then none of us are forgiven of our sins since this Jesus was only a man with grandiose ideas but no power to back it up.

            Anybody can die, but only one can rise again from the dead.
