This is… really not true at all.
LLMs differ from humans in a very very important way when it comes to language: we know the meanings of the words we use. LLMs do not “know” things, are unconcerned with “meanings”, and thus cannot be said to be “using” words in any meaningful way.
The academic consensus is that a guy probably existed who was a preacher whose teachings gave rise to the legend of this miraculous “Jesus”.
Everything that’s assumed to be real about Jesus is completely mundane. A preacher whose followers spread his teachings and fantastically embellished his achievements. Big deal! There are hundreds of guys like that. He’s L. Ron Hubbard without the trillion-year-old spaceships.
