Bones are hard because they must have the mechanical strength to support the weight of the animal (or the required proportion thereof, like in a whale) and facilitate the movement of that animal. Imagine trying to stand up if your leg bones were made of soft rubber. You couldn't. And could you reach across the table to pick up a glass of milk if your arm bones were made of that same soft rubber? Nope. Not happenin'.
They are hard because they contain a large proportion of calcium and phosphorus. In addition of providing leverage for movement (as noted above), they also protect parts of the body, like the brain, spinal cord, lungs, heart, and other internal organs. They also store minerals and make blood.
