We don't move through time, our perception of it changes. If we saw time as a dimension in space and looked at an unmoving ball, it would look like a cylinder with one rounded end at the point in time where it was created and one at the point where it was destroyed. A planet orbiting the sun would look like a helix spiraling along the path of the sun through the galaxy.

But our perception of time isn't broad enough. We only see one "instant" at a time, just a infinitesimal slice of the whole. We can see things changing but we can't see their whole existence at once.
