When someone tosses you a ball, do you do calculus to determine where your hand should be in order to catch the ball? Yeah, didn't think so.

That doesn't even make sense.

It makes as much sense as your observation that "Bees do calculus."

Just because there is a mathematical way to solve a problem does not mean that every solution to that problem was done mathematically.

Using calculus you can determine the flight path of a ball thrown to you and calculate the intercept point, but that's not how people catch objects in flight.
