God wrote wrote several.

Well first he had at least three guys write books for him (ghost authors?)

Then he branched out and wrote one in Arabic, and at some point he wrote another in the new world.

Another time he had some kind of revival and got a bunch of folks together to decide on which parts should be in his book, and they decided to put his first books in as a prologue, and added a whole bunch of new-wave hippy shit to it.

Then he picked some folks to translate it over centuries from one language to another, and then to another, and then eventually to English.

Oh but before your book from school, he even had some old English king decide to commission another "translation", 'cause he didn't like some parts.

Maybe your kids will get lucky and get the Trump bible in school, so that they can learn the US history.

Edit: ironically, I went to a school similar to your username

When you know its a troll but still downvote because fuck it

Little known fact, the original of the book God claimed to write sold so little it disappeared from history. There is no copy left, we don't even know what was in it. It just inspired fan fiction writes, that had insane success.
