I think that the reason that science and maths are so difficult for the human brain and therefor "unnatural" is that the human brain has a limited capacity, so it simplifies and compresses information together.

Just try to think back...What were you wearing 3 weeks ago at work? What did you have for breakfast a year ago today? Most likely you don't remember these details because they aren't relevant, so your brain forgets them. This has the net effect of making your brain NOT work logically and methodically, but rather through sensation and ascociation. The kinds of things the human brain is best at retaining are being with friends and family, first kisses, favorite foods, favorite smells, favorite places to walk, tramatic events.... things that effect us DIRECTLY and have relevace to our well being. This iswhy storytelling is so powerful. All stories are is is imagined reality, so we become attached to the characters as if they were real and we remember the story because it had some special message, or it had a funny ending, or whatever. And because we relate to good stories, our brinas remember them. In contrast, remembering things like the square root of 526, or the planets of Jupiter, or the periodic table of elements are more difficult because they havelittle to do with everyday life (outside of science) We have to force our mammalian brains to retain the information like a stubborn child.

So, when the inevitable question first popped in the mind of Early man "why are we here?" Is it really suprising that man's answer involved a story, rather than a desire to catalogue and analyze the physical world? Of course, the story was improved upon and revised, and more and more people beleived it over time.....
