I really understand where you are going but although a perfectly valid logical stance, you have to admit it's very tinfoil-ly and nihilistic.
I don't know if you believe in "unique truths" or nor, but with that amount of doubt, any truth gets practically impossible to establish.
I said it was "nihilistic" in the sense it is defeatist. If everything is part of a 5D chess plan from a powerful agency, we will always be powerless.
