This delusion that one of the kids that hung around was MJ's son.....

You probably know who I'm talking about, I just didn't want his name in the title since I don't even know if this subject will be allowed.
But I see these deluded fans saying over and over again that this boy is MJ's son, and they have these quotes from employees and MJ's father saying something they think means he's his son, blah blah.
And there's some kind of wild story about how his Norwegian mum was in the US once and met with MJ and had a son with him. It's crazy! And they believe it wholeheartedly and posts on his IG that he "looks like his father"...
Does anybody have any information that can explain this delusion? What makes them believe this? Is it a way to explain why he lived at Neverland for so long? Is it necessary in order to believe that MJ was not a pedo?

And why hasn't the guy gone out and debunked this? I sure would! Is he in some kind of contract with the MJ estate so he can't talk about anything MJ?

I don't get it, I don't get any of this, I feel like I'm in a crazy world when I see this claim.
And I'm from Norway myself btw, that's what makes this whole thing even weirder for me.
