ELI5: Why and how are we (humans) able to predict where a object will land (after thrown) and thus catch it?

We evolved to do this.  Humans have very unusual shoulder architecture compared to the other apes that gives us a unique leverage to throw things with great force and accuracy.

Once an object is airborne, the human brain is (with practice) extremely good at calculating the expected trajectory.  The physics involved is predictable and repeatable - gravity and air density do not change significantly, only wind.

We presumably evolved to be very good at this so that our spears and javelins could be lethal from great range when hunting.  You don't really want to get within kickin' distance of a water buffalo if you don't have to.
