Humans are always trying to figure stuff out. Humans forever try to understand the world around them, with experiments to prove or disprove hypotheses. Humans conduct research and investigate, they prod, and study and forever are on a path to infinitely try to get a better grasp on life and how things work- making up stories (religion) when science escapes them. Humans say that this makes them superior to other animals of the planet, but ever think that the other animals are superior for that same reason? Animals don't have to dedicate their lives to search for answers, because perhaps, they already know.
