"In Search of ..." examines evidence that life on earth began when extraterrestrials brought it here. The former NASA space scientist, Maurice Chatelain, who wrote "Our Ancestors Came from Outer Space," connected the sites of ancient Greek temples and found a pattern that he believes must have been influenced by aliens. He further believes ancient tablets from Iraq record aliens' cross-breeding experiments with humans. Another scientist has found what he says are electronic symbols in prehistoric rock carvings. And Preston Monongye, member of the Hopi Katsina Society, makes cryptic remarks about Hopi legends regarding spacecraft.
The program takes us to Death Valley to make an analogy between burros and humans; to Utah to show us a shellfish fossil embedded in what look like shoe prints; and to southwestern United States to examine how the folklore of American Indians may be real stories of alien visitors.
"There have been many theories which say that life has been deliberately sent to earth from another planet," says the host Leonard Nimoy. Some experts ridicule these ideas. And such theories might have remained unbelievable, except for disclosures such as these, which continue to be found year after year."
I'm not an expert, and I won't ridicule the ideas; but I know these types of programs are very selective about what they tell us. Monongye, from the Hopi society, frankly elides the facts when he tells us that he's not allowed to speak in more than generalities, because his religion forbids it. And the program asks us to come up with better explanations for their evidence than alien influence. Yet such "explanations" create more questions than they answer.
Still, this sort of thing is enjoyable as fiction. And I won't mock the ideas any more than I'd ridicule ancient myths.
