I love this circular one from the science textbooks. "The strata is calibrated by the geologic column" and " the geologic column is calibrated by the strata" . Ok... that means that both the geologic column and the strata findings interpretations are from fantasyland. The whole archaeology thing is a huge fantasy. I refuse to spend any time on it. Now if somebody is finding weird stuff that does not fit the fantasy, I am interested. It might lead to some truth.
