Can we use Present perfect tense to talk about past?

Question

In a given linked video (around 1:09) Mom is explaining past to her daughter. But While explaining her she used Present perfect tense in between, why? Is to correct to use?

Girl: Mom, so why are we white?

Mom: Well, one day, God was passing through a park, and he noticed the beautiful little black girl sitting alone playing with the white clay. She was trying to make a doll for her to play with. He stopped there to watch her closely. Her beautiful little hands were full of white clay. She has almost painted herself with the white clay, and he was amused to see her. So he decided to make more people and paint them white.

Answer 1

No, it's anomalous.

I agree with the transcription, but I don't think a native speaker would say this, except by mistake.

It's possible to tell a story in the "narrative present" - God is passing ... She is trying to make ... Her ... hands are full ... She has almost painted ...; but it's distinctly odd to slip into the present for just one sentence.

It's either a slip of the tongue, or her non-native command of English. I suspect the first.
