Well, we are the products of our environment, basically, we are wired to survive predators, competing predators, elusive preys, etc... Unfortunately for us, that does not mean being very good at finding deep abstract truths about the Universe. That's probably why as a species we are really bad at it. Just think about how much harder it is for a child to learn basic mathematical principles than it is to learn their mother language (something arguably a great deal more complex!!!).
