A lot of humans' brains' power comes from the fact that we have an ego and THINK our brain is more powerful when in reality it is just structurally different and just as limited to the same genetic confines as all living creatures.

Our conscious attention makes errors because it is so complex. The brain is not supposed to function in a perfect manner that creates a perfect perception of reality and functions perfectly to its environment but instead the brain is to function just well enough to keep you alive and mating. Its job is to make a perception of reality just accurate enough to keep you alive but it must simplify reality because our brain is nowhere near powerful enough to be able to accurately perceive our reality yet alone how to attend to it perfectly so it does the best it can.
