Jesus. Imagine how much of the world would react if
1: jesus literally proved he existed to faiths that say he's a hoax (im agnostic btw)
2: He reforms the groups that use his name as a pretext to exclude & marginalize others.
3: Dude turned out to have been gaming like a boss in heaven, like dude comes down & faces the pope in Dungeons & Dragons or Pokemon lmfaooo
