Because very precisely throwing a ball using the human muskulo-skeletal system is an extraordinarily difficult and complicated problem, not easily amenable to symbolic analysis. Even stating the problem precisely (on paper) requires PhD-level physics/math, there are dozens of moving parts involved, the timing of various actions must be perfectly choreographed, and the system is constantly changing.
