Wrong isn't the same as incomplete and we have a weird tendency to overlook things, we find then "obvious" afterwards. Things we do not easily perceive are such that are too fast, too small, too high energy generally and, most importantly, too unexpected. Further, you can hide in plain sight: you only have to look "unbelievable" (for example), so society will not transmit the information of your sighting. You can hide where (nearly) no one is looking as well: deep under the ocean, far below the surface, high in the sky, etc. Most likely, this isn't exhaustive. Places we don't know about are perfect for hiding ,-)
