But it still doesnt make it the absolute truth until you can see it clearly.

Sometimes doesnt = 100%
I can't believe this thread has not been closed.
I deal with evidence and procedures in my daily professional life, and nobody can convince me that there is a conspiracy swirling around property corners. Yes, some greedy or dishonest person may move one to benefit himself, but we can restore it to its proper location. It's very hard to fool a land surveyor. It can happen occasionally, but not most of the time. More importantly, when those rare occasions occur, the conditions are not dictated by the dishonest landowner, but a series of neglects to the records and the properties. There's no conspiracies in this critical business.
That being said, we can never see anything 100% clearly. The events that have happened cannot be played back like we had a time machine; we can only sift the evidence and put the pieces together as clearly as we can in a systematic manner and come up with a conclusion that would hold up if we went to court. We constantly have a judge "sitting on our shoulders" so to speak. Our conclusions have to stand the test of reasonableness to our peers and to the court.
If I had to go to court and convince a judge and jury that there is a vast conspiracy to defraud the citizens of their land by the UN, I'd not only get laughed out of court, but lose my license to boot. And rightly so.
Belief systems (of which conspiracy theories are part of) are really all the same, and they are a manifestation of an untrained brain, or in some cases, an abnormal one. Paranoid and delusional thinking are not normal or healthy thought processes. As a matter of fact, these are the very characteristics of those who do the school shootings and other horrific acts.
This nicely sums it up by the famous German genius:
"A casual stroll through the lunatic asylum shows that faith does not prove anything." — Friedrich Nietzsche
