I like Clif and I listen to him, do I agree with all he says no, but that’s the point of listening to others saying their perceived viewpoint it’s brings up debate and intelligence conversations, to discuss like the comments here. I do agree with him on the fact that large portions of our history could be missing or changed, yes look at what they are doing now. Also he brought up that during the 1800’s several large cities saw fires that took out good portions of businesses, and could have destroyed history, so we would not know facts, point being? What if these were intentional? We don’t know but, with what we have seen so far it could be possible. When I hear dates put out no one knows how long anything will be so I keep that in mind only God knows.
