Query: Unadulterated Hokum!

This series is pure speculation and conjecture without showing a shred of credible evidence. The concept that everything on earth related to the history of mankind, religion, culture, discoveries, grandiose ancient structures, etc., happened because of ancient aliens is ridiculous. It's comedic to see fiction and speculation excruciatingly made to look like fact. The pure hokum science throughout the episodes would have made for good science fiction entertainment, except that it repeats itself nauseatingly. Hey, with a canard presented many times over, the gullible will buy the story hook line and sinker, and come back for more. Pure comedy indeed.
