That's assuming that what's going on is that entities who are essentially based on the same lawful universe as we are are running circles around humans. If what's going on is instead something like a weird universe, where reality makes sense most of the time, but not always, I imagine you might get something that looks a lot like some of the reported weirdness. Transient entities that don't make sense leaking through the seams, never quite leaving the causal trail which would incontrovertibly point to their existence.
