I'll try. It's a lot easier to be hidden from the perception of something that isn't even capable of perceiving itself or its surroundings, only reacting to simple stimuli. A lot of animals are smart enough to at least get a pretty decent picture of us. It could maybe follow that there are beings that we would be unable to really comprehend the way we comprehend other humans. But it would also be pretty likely that we could develop models, heuristics and statistical analysis to extract meaning about these theoretically confusing aliens. We understand quite a bit about our society- which is basically a hyper complicated animal. We deal with the gaps in absolute knowledge pretty well.
