religion = people asking money so you can gain favor from the gods.
in the old nordic religion, priests (called godar)
controlled rituals to please the gods and sometimes told the future (basically it was a system of you give this guy a rabbit or something and he cuts it open and either "reads" the future in its intestines (no idea why)
or spills the blood over some statue and says some crap to please the attendee.
the rabbit or whatnot is of course left behind for the gods (who do you think ate it and got a regular nice meal for putting up a bit of a show?
then of course this turned into more "big" affairs as the "priests" influence grew..
how it started? well, i think it might have gone something like this.
Thunder rolls in the distance, 2 skinclad men are sitting there tending a flock of sheep, they get to talking
"what do you think that is rolf?" "maybe its a big guy that does that hans"
"really" "yeah, i mean what else can it be? only thing around that creates stuff is us and we cant do that, so it gotta be bigger people"
years pass and since tending sheep is really boring, this gets to be the main conversation (since this is a area where thunderstorms happen alot it gets compounded)
and later on the big people get called gods and get names like thor.
years pass again and some bit natural disaster happens, everyone is shitscared.
and one dude, thinks aloud
"i wonder if the gods are angry"
"i wonder if we can please them"
"so..what do they like?"
"well, i like sheep"
so they try to sacrifice a sheep and offer it unto the heavens.
coincidentally, the natural distaster stops at the exact same time.
and now the guy that thought of this is a really important guy.
and so on. lol , maybe
