We know it does rotate.
We know its slowing down 2.2 sec every 100,000 years.
We understand earth rotation effects the shape of our planet and its gravity.
My best guess is that rotation of the planet is what allowed the planet to form and survive the suns gravity...perhaps initiated by the forming of the solar system following the big band...albeit long after. ergo all planets that didnt spin, didnt survive.

Which planet will spin the quickest? All the planets spin, the sun spins, the gas giants spin, moons spin. An affect you call gravity is working on all of them. Pluto is miles away. Which planet will spin the quickest?
The facts are
The rotation period for the main bodies in our solar system are
mercury 59 earth days,
venus 243,
earth 24,
moon 27,
mars 25 days,
jupiter 9.93 hours,
Saturn 11 hours,
Uranus 17 hours,
neptune 16 hours,
pluto 6 days
The sun makes a comple spin every 34 earth days at its poles yet 25 days on its equator
The largest of all the planets spins the quickest, it is a big gas ball. Those planets further away from us spin quicker than the inner planets.
The moon spins around the earth on such a precise random spin that we only see one side of it.
Some of the moons of Jupiter even spins against its own direction of rotation.
An important question is is why do we have 2 high tides when we on earth only spin round only once in that time? The moon is not the one moving in the sky, we are. The answer is to do with why we and everything spins. You can see it before your very eyes if you ever see the Northern or Southern Lights.
Magnetic fields are caused by the flow of electrical current. Electrical currents need a conductor and in space that is called plasma. The planents and the suns spin speed is due to power of the magnetic force created by the strength of the electric current flowing through them all. The Northern and Southern Lights are just natural versions in the sky of what we have artificially created in and call Neon lights.

The earth is still revolving from the angular momentum it got from it's creation when dust, rock, and large collisions coalesced to form the earth, almost 10 billion years after the big bang. Also, the earth increased it's spin when billions of years ago, a proto planet the size of mars smashed into the earth at an angle; the debris of which coalesced into the moon. The earth has been spinning ever since because of the conservation of angular momentum. The earth's spin is slowing down because of the tidal drag on the oceans caused by the moon and the sun, so there is no force causing the earth to spin, but there is a force causing the earth to slow it's rotation.

After the impact that created the moon happened, Earth's day was about 10 hours long. The newly formed moon was much closer to Earth than it is today, and this created a huge tidal bulge. This bulge was pulled on by the moon, and it has slowed Earths rotation (and continues to slow it today), to our now-24 hour day.
If the moon were suddenly taken away, there'd be no slowing of Earth's rotation - we'd continue to spin at the same rate because there wouldn't be any force slowing us down.

No, it has nothing at all to do with the big bang. That created the universe. The solar system formed about 10 billion years after that event. The driving force is gravity. The sun pulls at the planets, but because the planets are moving they never fall into the sun. Its called an orbit.

a simple thought, think of the earth as a giant spherical magnet with its north and south pole. As with every magnetic force there will be a field of transfer between the poles. Add to this a known attraction between the sun and earth. Add to that the affect temperature change has on magnetic force fields and you might create a revolving spherical magnet.

Every thing out there is revolving just as when the dust clouds formed.

There is no force. Earth is "coasting" on the momentum it got from its formation.

it is a very heavy bit of rock, there is no friction on the bearings, it will spin for ages

its just kenetic energy fro then world bein made whilst it was just gasses they were swerling then it sildified still spiining aND SOME OTHER THEROIES ARE THAT ITS FROM HUGE COMMETS HITTING US SIDE MON BUT WE WILL EVENTUALLY STOP SPINNING
