Somehow all things in your life are complex there for should be complex answers to questions. Sorry you don't get to choose what is in the world.
I could flip that around and say that "somehow all things in your life are simple, therefore there should be simple answers to questions." You seem to fear a world that you cannot easily understand.
You crave simplicity, and yet, paradoxically, you come up with increasingly complex explanations as to why things are the way they are just to weasel around the evidence.
If there's good evidence, accept it. If there isn't, move on.
