The 2400 years later this guy arrives in Jerusalem saying he is the messiah, the son of God.
he lives a pretty boring life, so he decides to become a first century Walter Mitty. He makes up a few stories, his friends make up some more, others exaggerate them, pretty soon this ordinary guy is working miracles, raising the dead, and even came back from the dead himself. The stories are so convincing that 2 billion people now think they are true.
It is a nice explanation you have, but it then opens up the possibility that the entire Bible is a work of fiction.
