I tend to make my own mind up about stuff I read I've said it before here all history is best guess. A number of witnesses to the same modern event will give different stories. That's when they are attempting to tell the truth and not have vested interests to promote or positions/ego's to maintain. Anybody that tells you something is certain historically is telling porkies. Sure somebody built the pyramids and there is a high probability not certainty that it was ancient Egyptians BUT it may not have been something or somebody else that designed them. When something is impossible to prove then alternate views are inevitable. They too have probabilities some more believable than others.
