First observe the proof that you are unable to overturn then the consequences of what Jesus said if you continue to shut your mind down to the proof.

The proof is since almost all scholars agree for "good reasons" the disciples truly believed they had seen Jesus alive from the dead in various group settings, talked with Him, walked with Him, touched Him and even ate with Him then this is a fact we can glean from the Scriptures and be 100% sure about.

You need a naturalistic explanation to account for the origin of the disciples' beliefs. If you can't find one yet still refuse to come to the cross as a helpless sinner to receive the Lord Jesus as Savior then you are "without excuse."

Elementary dear Watson.
