Earth can't really rotate around itself. That's really hard to do.

When the the solar system was young and the sun had not even formed yet the solar system was just a gas cloud, about the same as density as smoke. Now because of gravity all of this gas started to clump together. The biggest clump (the modern day sun) was at the very center, as it got bigger and bigger it began to pull all the other gas toward it in a spinning motion, this spinning motion is what caused modern day planets to eventually orbit the sun. There were other smaller clumps of gas that began to form as well, these are our modern day planets. They also spun as they collected more and more gas.

Conversation of angular momentum in this case.  But the fact that angular momentum is preserved is not as intuitive as linear momentum.

The earth "spins" (rotates) on its axis based on the action of the materials that accreted to form it, and also on any large collisions it might have undergone. Like the one in the large impactor theory about the way the moon came to be in orbit about the earth.
