When you say the Earth takes 24 hours to rotate, you're ignoring the orbital day/night cycle.

The next person who explains why the South Pole station has moved out of
darkness will also be explaining where the Equation of Time comes from along
with the seasons at lower latitudes.

And here I thought this happened at the South Pole because rotation doesn't move it, it only turns it, so only the orbital effect governs day and night there. (It's not at the ecliptic pole, or it would have eternal twilight.)

Enough of the anti-astronomical,anti-faith crowd,

Astronomy is part of science, not part of religion.
