Sorry, but that effect can also be achieved by the Sun orbiting the earth.
I'll admit it IS interesting and thought provoking, notwithstanding the hecklers. When you think about the conventional wisdom that the Earth is hurtling eastward at, what, 1000 mph, why are objects as ephemeral as clouds apparently moving in tandem? Why wouldn't they be losing the race at some point due to the declining strength of the molecular pull?
In other words, if I am on a carousel and holding out a steel rod, it will certainly move in tandem with me because it is solid and connected. But if a hold out a balloon on a string, it will quickly lag behind.
Hmmm.

OK - how about this - why does water circle one way in the Northern Hemisphere when going down a drain and circle the other way in the Southern Hemisphere? If the world was stationary - it wouldn't spin at all.
That should prove the Earth's rotation.
