I wish "Jesus "would have posthumously signed the gospels, verifying his supporting the Adam & Eve, Noah stories. Cleaned up my library, gave away "Mein Krampf", and they asked whether is was a signed copy. so, these can be gifts, authorisations, a product of treasure hunters.
Imagine if one could disprove wt doctrine to them from their signed copy, or argue a [heavenly] judgement case that way.
