The Fomeko chronology is entertainingly batshit, with a history-rewriting conspiracy of crazy scope and petty motivation. It makes vanishing a few centuries look like small potatoes.
I think the touch that the New Testament actually refers to events prior to those of the Old Testament is particularly fun.

A common theme is attempting to tie the Bible in with the rest of history.
