Sunlight does not help us to make calcium, but it does help us to make vitamin D, which we need to use the calcium that we have; the two work together. When sunlight shines on our skin, we can use that energy to drive a photosynthetic reaction, which is not unlike the way green plants use sunlight to manufacture sugar.
vitamin D
Bones are strong because of calcium. This is a mineral that is very hard and forms the framework of all bones. Vitamin D helps the body to form bone from calcium. Humans find vitamin D in lots of things, like the sun, milk and other food.

The skin uses the sun to produce vitamin D. It is not literally absorbed through the skin from the sun, rather vitamin D is produced by the body under the skin in reaction to sunlight. Vitamin D is necessary to keep bones and teeth healthy as it helps to regulate the amounts of phosphate and calcium in the body.
A bit can be good for you, it will help your body make a few essential vitamins. But too much (particularly getting sun burned) will make the skin age faster and increases the risk of you developing skin cancer.
it gives you rays that help your bones and teeth grow

Daily exercise will assist with the production of vitamin D, but in order to get it more proficiently, your skin will absorb the Sun's rays. Now this can be good, but also be bad. For instance, you could develop skin cancer.
