Insulin provides a way for your body to control how fast it uses the energy you eat, and when. If it weren't for insulin, you'd be low-energy when hungry, and high-energy right after a meal, which would make hunting new food very difficult.

You'd probably starve to death the first time you didn't eat for a while, since without insulin you'd be unable to save your energy for when you need it most, so you'd be too weak to go find (hunt?) more food.

What it actually does is simple. Glucose in your blood provides the fuel for almost all body functions. But your body's cells can't admit glucose for fuel without a small amount of insulin present, to indicate 'permission' to consume that energy. That insulin is produced by the beta cells of the pancreas.
