why does the night sky not look like a long exposure camera shot if the earth is spinning and the light from distant stars takes so long to get here?

Answer 1

It takes a long time to get here, but the light is still moving fast. By the time the stars appreciably move in the sky, the light from their old position appears to come from the new position. A long exposure shot shows those streaks because there’s no light being generated, only what was recorded in the shot.
