What historical evidence suggests the story about Pocahontas saving John Smiths life did not happen?

It was part of a movie not irl

It says that he hasn’t described any threat of execution in his expedition and it was to mock the execution ceremony that natives males have to go though

They would never unalive a prisoner someone in that way. They would have burned or tortured him instead.
That and she was 13 so…… take that how you will

Do you have to corresponding answers if not i believe it was live stock and food/supplies hoped this don't forgwtg to rate me up : )
