[stubish]

A human experiments, predicts, learns and understands. A baby shoves everything in its mouth. It discovers how its actions affect the world, extrapolates, and experiments. It learns metaphor, learns how metaphor is useful to predict similar systems, learns the limitations of metaphor. It isn't just gorging data, it is creating data. It fills in the blanks with guesses and superstition, and maybe even uses reasoning to confirm it's speculation. A baby doesn't just regurgitate, no matter what a sleep deprived parent might think.
