We didn't make it that way. We observed it. Math is neither a superset nor a subset of nature. It's a protocol, expressed in many languages including base 12 and Roman Numerals. Our scale, the decimal point that was the atom, then the quark and string, and now this geometric construct is relative. The microcosm is the macrocosm.
EDIT: Smell consists of extremely quantifiable microscopic particles affecting our nervous system.
Don't be such a
philosophical zombie!

I was talking about the 100s of
feelings of smell. E.g.: "wow, this rose smell is beautifully
rosy!"* Instead of "Alert! My atmospheric sensors are detecting aromatic carbon chains number 485! Exterminate them!"

*Notice how those descriptions of qualia are always tautological? A rose smells rosy. Red looks red. Blue looks blue. A high-pitched squeal sounds like a high-pitched squeal. Of course, whether
my sensation of blue is the same as
yours, is another matter. That's why the
Wikipedia page on qualia is so huge, it seems that scientists don't know where to start with things we know absolutely but cannot prove. Blue always looks "blue" to everyone who can see blue? Or "sensory relativism", kinda like synaesthesia but mixed between different people?
I'm glad we agree. The assertion of intelligent design belongs in the hazy realm of subjective qualia, not fact, physics, math or science.
EDIT: I'm a behaviorist. I'm immune to the P zombie argument.
