Shuckins, if you believe your bible, you can blame that directly on Adam & Eve.
Only mankind has eaten from the tree of knowledge of good and evil.
All the other animals are "innocents" they lack the capability to consider those things. As to why so many people do bad things they shouldn't, well maybe, just maybe they are reverting back to animals.
Furball, Star Wars "IS" my religion.
Well a part of it anyway.
Believe in the force!
What do you think a "Jedi" is? A warrior monk? A future age Knight Templar?
As for religion on the grand scale, it is my belief that.
A If enough people believe strongly enough in "something" whatever that might be. That will eventually call or will that "being" into existence. Perhaps not as a person, ie I don't expect to see superman buzzing NY,NY. But on a spiritual/god level.
B Given enough time (2k years) Mankind can screw up ANYTHING. Including a religion. My point, all of the "kosher" food & diet rules, regulations stemmed from a single admonition. "Thou shalt not seeth (boil) a Kid in its own mothers milk". Some 2000 years later that has been argued over, interpreted, played with, adjusted and tweaked to become the vast mass of rules known as Kosher.
C If you can imagine something, a concept, a force, a Magick if you will.
If you can completely grasp all of it, and all of its implications. If you can see yourself bring this into existence by sheer force of willpower. And if you can "Believe" that you can do this now, that you DID just do this. (Shades of starwars, there is no try, there is do or do not)
Then you can do Magick, you can make things happen for which there is no explanation. Call it mysticism, call it force of character or will, call it belief. Call it what you will.
