. . . The book could actually be used as a great learning tool . . .
I’m not sure the book would have enough to bite down at. Intentionally or not, van Daniken may have picked examples, such as the Nazca lines in what’s now modern day Peru, which are not well known.
This could be done innocently. For example, a creationist scientist may truly believe the hemoglobin molecule shows the handiwork of God, and believes the half-step forms are not evolutionarily useful. And if it’s the case that there also happens not to be much research on these half-step forms, well, there you go. That’s a full chapter in at least one book!
PS You seem like a thoroughly alright person. I’m sorry you had to go through war in ex-Yugo and Croatia.
PPS And Congrats on Croatia beating Russia in the World Cup!
