Earth consists of a large amount of material that clumped into a ball in space due to gravity. Before it collapsed the material already had some spin to it. That was because objects in orbit around the sun travel at different speeds based on their distance from the sun, with further objects moving slower. That the material clumped into a ball did not stop it from continuing to spin in space. One of Newton's laws of motion is that, in a mathematically precise sense, the spinning of things stays the same unless that spinning is given to something else. But since the Earth is floating in space there is nothing else for the Earth to give spin.
