Sorry, Cecil, it isn't an illusion. Sunrise and sunset are simply names

You can believe that the sun rises and sets if you want to,
Dave. Most of us know that the sun is fixed at the center
of the solar system. The names "sun rise" and "sun set" were
coined back when humans believed that the sun actually made
a trip across the sky every day over a flat earth. Do you also
believe in a flat earth?
