I know how these people exaggerate and how they come up with all those gods and stories and mythology by over stating things and matters by exaggeration. I don't believe most of the things actually happened, not even the tiger was present in his journey. It's all made up by a boy who just survived a ship crash and maybe had hallucinations and made up all those stories. Except those VFX movie has nothing as nothing is believable in the first place.
