ELIEIGHT: why don't we feel the earth moving?

My daughter posed this question on me, asking why we can't feel the rotation of the earth even if it's going at such great speeds. I gave a weak ass explanation about it probably having to do with gravity. So what is a more apt explanation?

Because it's moving at (for all intents and purposes) a *constant* speed.  We feel acceleration, not speed.  (Think about driving in a car or flying in a plane--do you feel steady-state motion?)

An interesting caveat to this is the Coriolis effect, which can actually make missiles and planes seem to accelerate when traveling between different latitudes, but that's a different question.
