sNaP!
I know what you mean. I was entranced in my younger years by documentaries on UFOs and the Kennedy Assassination; yet, many years later, I find the newer documentaries regurgitating up the same “evidence.” I tired of it all.
There was a documentary on the History Channel where they traced back DNA to the original source of man, and they came to the Bushmen of Africa as having the first “marker” in their genetic makeup. Interestingly enough, there had to be a source before the Bushmen that had no markers. A single source! A single primate? I doubt it.
Also, archaeologists have long searched for the “missing link” without success. Maybe because there isn’t one?
