Math Physics Chemistry Biology

Folks like to cite counting as being the earliest form of inquiry making Physics, Chemistry and other fields subcategories. I take offense to that. Physics came before any math as did chemistry. Physics in the form of clubs or rocks to hit or throw to kill prey. Chemical materials to flavor foods, color things (dyes), tripping, etc. Fire. Mathematics was created in order to quantify much of what primate man knew and used. Mathematics approx 20,000 yrs ago. Cave drawings, fire, rocks to use as weapons 250,000 - 1M yrs ago or more.
