the reasoning for rotation at a rate of 15 degrees per hour...

Years ago I had a telescope with a clock drive and a drive corrector,
it enabled me to track the stars. It also had a switch for "solar
rate" and a switch for "lunar rate". These were needed because the sun
and the moon move across the sky at a different rate than do the
stars. Of course, this is because the moon orbits the earth, and the
earth orbits the sun. Why is this so hard for you to grasp? Forgetting
about the moon, it is quite clear that 360 degrees with respect to the
sun is different than 360 degrees with respect to the stars, and you
can prove this to yourself night after night and day after day. The
difference is about 4 minutes a day. This is empirical data in its
simplest form, anyone can measure this.

You find this extremely difficult to absorb because your educational
foundation is lacking. My 14 year-old granddaughter, however, has no
problem at all resolving this "mystery", I have made sure that her
foundation is built on solid ground.
