Hey, Bob,
Here's a logical demonstration:
If "sh!t happens (...) randomly" and we have no way to fully control it, predict it and prevent it, that must mean there's always a chance of being surprised. If that's true, there's always a chance of being wrong.
If there is a constant chance of being wrong there's not a single thing we, human beings, actually know (that, assuming human beings exist).
So, if we know nothing, any concept we call "knowledge" is in fact just a belief, and not a fact.

Are you still with me?
If what I wrote is true, and it is, because it's pure La Palice logic, what you "know" is just a set of beliefs, and belief is just the result of indoctrination. Evidence is irrelevent because it's the reflex of collective dogmas.
Isolated entities, individual or collective, will mentally mutate and diverge on even the most basic beliefs.
When two cultures are isolated they will eventually diverge on things like human rights.
When someone starts being somewhat anti-social, he will start believing/knowing things differently than what the community he's inserted in believes/knows. Then conflict happens.
You are, to me and I think yourself, an evidence of that; understanding what I just wrote results in understanding that you are trying to impose your beliefs and the things you think are evident on people who think differently, through the media, the same way they must have tried to impose theirs to you.
By accepting the logical validity of these conclusions, if "sh!t happens (...) randomly", it should be obvious that any conspiracy theory is as evident as gravity.
Nice one, is it? Please applause. xD
