My fringe hypothesis is even wilder:

Jesus told his believers to eat his flesh and blood to get eternal life (John 6:53–57)

Someone took it literally and opened the grave, and ate the body

This is how the body disappeared suddenly and the grave was open. Others seeing this thought this was a miracle. Meaning Jesus came back to life, opened the grave and left

Whoever was involved had a good reason to keep that secret
