It seems a lot of these reviews are purely subjective in nature. Mostly derived by feelings instead of a more disciplined mind to be objective with the review. Not really something I would put my trust in when reviewers would rather label a person as "arrogant" or have a "superiority complex", these are just subjective opinions nothing more. If you break down the word history it literally is two words combined His-Story. Which is clear that it is stories passed on and only deciphered by the TOOL we use called science.
To dismiss the idea that history with the help of science is always refining itself is not being objective at all. Just like science is always refining itself with the new knowledge presented, so is the history we barely know as well. There is a reason why myths/stories have survived for so long, whose to truly say there is not any ancient wisdom within it?
Mr. Hancock does well not to state that his idea is absolute (he knows it well if one bypasses there own subjective bias to truly listen) while remaining open with objectivity to relay that maybe we should have a more thorough look at not only the stories that have lived on but the story the earth provides as well. If history is nothing more than someone's story, then who is the overlord telling it today to say it is the definite story with no room for discussion or change? Don't let objectivity die to spare egos and feelings.
