Since you have no evidence whatsoever, you are the dad
And do you have any evidence that you are not the father?
Even though he and that woman barely met, she already asked for a request Michael doesn't really understand. "I said don't mind, but what do you mean, I am the one, Who will dance on the floor in the round, She told me her name was Billie Jean, as she caused a scene" (Jackson 2-5)
Never doubt a "mom"!
There's no way...?!
Michael doesn't understand how he could be a dad even though he has a strong belief that he doesn't have a son. "She's just a girl who claims that I am the one, But the kid is not my son" (Jackson 13-14)
You'll see sooner or later!
He wanted to explain that he doesn't have a son, but he had no evidence and no one believed him. "The law was on her side, But who can stand when she's in demand" (Jackson 18-19)
She's not my lover she's not my lover she's not my lover she's not my lover she's not my lover
She showed him a picture of their baby with something inherited from Michael "Then showed a photo my baby cried his eyes were like mine" (Jackson 25)
What are you guys talking about...?
Afterwards, Michael gets nervous everytime he meets with her. "This happened much too soon, She called me to her room" (Jackson 31-32)
What do you want...
Even though she showed Michael some evidence that the child is his, he keeps telling himself it isn't real. "Billie Jean is not my lover (x5)" (Jackson 48-52) Making the mood seem baffled, and the tone sound resigning. The theme showing that MIchael would have to accept what is around him instead of denying.
