There is no leap! Let me ask you this... how do you control a growing population of people while still maintaning social order?? Give them a "religion" based on FEAR- so even if the human "authorities" didn't see you do, the scary spirits did and you be punished!
The WT org uses this same method today to gain control of your average JO/Jill for their own sick and twisted reasons right? Why do you think they are soooo in love with the original cult known today as the Jewish Faith???
Bravo to the original writers of the Torah... what a way to mind-f#ck the whole planet into believeing in the "boogy monster" (aka Satan), and scamming billions of dollars out of people for the last 4 thousand years!!! I take my hat off to you Well Done!
