Neither FET nor RET is easy to explain, beyond "The Earth is roughly flat" or "The Earth is approximately spherical."
No, you can go a lot further, at least with round Earth.
For example:
The sun appears to set because it's relative position puts Earth itself in the way.
Objects going over the horizon disappear from the bottom up because of Earth obstructing the view.
The moon's phases are based upon the moon being illuminated by the sun and its relative positioning resulting in us seeing a different amount of lit/unlit.
Day and night is caused by the rotation of Earth with the sun illuminating roughly half of Earth.
The seasons are caused by Earth's axial tilt, combined with its orbit, making the sun appear to trace a path on the celestial sphere.
The different apparent position of celestial objects is primarily due to the different orientation of Earth. For example, Polaris, situated roughly above the north pole, is visible at an angle of elevation equal to your latitude, and is not visible significantly below the equator as Earth gets in the way (taking the latitude here to be negative).
There are 2 celestial poles because the axis of rotation of Earth goes through the celestial sphere at 2 points. These are always 180 degrees apart because they are 2 points on a straight line they are so far from Earth they may as well be infinitely far away.
People fall to Earth, and the planets all orbit for the same reason of gravity with masses being attracted to other masses. We fall to Earth because it is the most significant mass near us, and all the planets orbit the sun because it is the most significant mass near them.
Photos from space show Earth is round because Earth is round.
Earth can be circumnavigated in any direction because Earth is round.
And so on.
There is plenty that can easily be explained for a RE.
None of that applies for a FE.
FE needs numerous contradictory models to even begin to explain it and plenty of their so called "explanations" will contradict the "evidence" they provide to support a FE.
