The “hallucination” argument is untenable. There is no such thing as shared hallucinations.

Thousands knew Jesus before the resurrection.

There is no plausible scenario for anyone taking the body from the tomb.

There is no such thing as shared hallucinations.

There is such a thing a shared false memories.

I recall, but do not have a source, that such a thing has repeatedly been demonstrated.

There is an event. Someone claims something happened, which did not, in fact happen, and the "false memory" spreads by word of mouth.

Soon, a significant number of people remember the claim as reality.

Even the orignator of the false memory may have mis-interpreted what happened.
