Perhaps one day we'll discover that evolution does not present the whole picture of how intelligent human life arrived, but that time has not come yet (needless to say the answer does not come from the absurd genesis account which requires even more rapid evolution after the fall from grace). As Richard Dawkins said in his TV series Enemies of Reason, "we should have an open mind, but not a mind so open that our brains fall out".
It became clear that this guy is a nutter when he started talking about "hominoids" such as bigfoot and yhettis that still exist (I could have sworn he said that

). Not to mention the fact that he bases the entire thing on the ideas of the ancient Sumerians. Is there
really any evidence that we were genetically engineered by a race called the "Nibiru" orbiting the tenth planet? I think not. We must always have evidence. We do not simply believe any story that floats past our front window just because it provides us with "answers". It is better to have no answers than the wrong ones. Further, it would be very bad to "get the right answers for the wrong reasons" (although that does not apply here).
He says a lot and explains very little. If a person says something it is imperative that he backs it up. THis sort of stuff is targeted at people with little science education, because they don't know the methods of research. This guy says that he "researched" it thoroughly but tells us nothing about how he did that. Besides the highly questionable beliefs of the Sumerians, what evidence does he present? What data did he collect? How did he analyse the data? Was his study peer-reviewed? Has he been backed by experts in Astronomy and genetics?
One of the tell-tale signs of a scam is when they announce their "findings" via the
media, who will lap up any story for ratings. Recently a company called D-wave systems did this. They by-passed the established peer review system and held a "conference" using the media to say they had built a quantum computer, something which is decades away. They do this because they would never get past first base in a proper peer review. Another way con-artists do this is by publishing a book, rather than a paper in an academic journal. In other words, it's all to make money. Books like this make millions even though the content is worthess. In my country books like that outsell real science books by almost an order of magnitude. I have to wonder what this says about our society.
By the way Mutant Hippie, I don't mean to rain on your parade or anything else, if that's what I've done.

Actually the fact that you said you don't fully understand it is a good sign. If something seems to not make sense, then either: 1/ the instructor is very poor at explanation, or 2/ it actually doesn't make sense! I suspect that here it is the latter.
