Thanks for the link, C.I. most of that info was in my link, I think. In the movie, book, whatever--Blatty was suggesting that the arrangement of molecules that many think came together to evolve into man was not by chance. He used the movie as a vehicle to espouse his probing. I really believe that he wrote that book as a result of the horror that circulated after the Exorcist. Mr. Wizard and I have briefly discussed this before.
(sooooo, I used a split infinitive)
