If you mean soil, it's a combination of eroded rocks, and decomposed plant and animal matter.
If you mean like dust around the house, it's mostly little flakes of your skin and hair, and that of any people or pets that live with you.

Dirt comes from the weathering of rocks it's called Pedogenesis. The rock breaks down and forms the soil. Check out the link for some info.
