Nope, you've got it wrong.
Fear was most probably the first motivator for supernatural, that is religion. After that, somebody offered security through religion as well, hence we found all this bullshit (-> goverment etc).
You can fool people into believing any shit that makes zero sense if they don't have tools in their mind to deconstruct and detect bullshit of that particular kind. Religion, government, sects, racism, nationalism, divine right of kings, human sacrifice as part of some ritual (fear?) etc... I'm not saying everything in this paragraph makes zero sence but stil.
Everything social in this world works because something or somebody has some kind of interest in doing things that particular way... no matter how small it may be or how stupid (just liking the religion?).
http://www.clearbits.net/torrents/164-god-wants-you-deadHere is some food for your thoughts...

Gives a nice explanation about how ideas work, spread, and become what they become (religion, government, etc)
Basically, the first two chapters explain the important stuff, the rest is the first two chapters in terms of different ideas like religion, government, simple memes like "look both sides when you cross a street" etc...
Let me know what you think if you happen to browse the book (and yes, this is a legal torrent).
