Only the judgement of history can make such claims.
IIRC it was not the kid himself who originally made the claims, but some nutcase Buddhists (or con men), and they made the claim when the kid was way too young to have any involvement in hatching a scheme. The kid may or may not believe the story now, but I think he grew up being led by others to believe it. Maybe he's starting to get a clue that it's all a bunch of BS.
And as I think of it.... Jesus didn't make that claim. It was, John, the voice from the cloud and then Peter. Actually, His mother was the first to tell Him to do a miracle. He did finally confirm the "accusation" of the High Priest at the beginning of his ordeal and later Pilot asked Him whether He was King of the Jews and He said "yes."
"When someone claims to be holy, let alone godlike, or even god-on-earth, I have to laugh.
Only the judgement of history can make such claims."
So, 2000 years ago, when Christ was walking around saying He was the Son of God, you would have laughed?
Just asking.
