Aim a lot lower - try not knowing what causes the basic hemispherical
seasonal variations in daylight/darkness and that dismal fact is a
100% certainty

I fear your "basics" are still too sophisticated for them.

Yes.

I asked them to recognize two specifics 360 degree motions with
respect to the central Sun from direct observations of another planet
and they cannot manage that -

A planet's daily rotation through 360 degrees generates the day and
night cycle while the separate slow turning of a location through 360
degrees with respect to the central Sun,seen by the longitudinal
motion of the Equatorial rings is responsible for seasonal variations
in daylight/darkness -

Copernicus did not have the availibility of telescopes to reason it
out via planetary comparisons how to explain the seasons in a more
productive way that the 'axial tilt' explanation which is still used
today.Extracting that 360 degree orbital component is indeed tricky as
it exists over and above orbital motion around the Sun yet I doubt if
even the Mensa crowd could interpret the images above of Uranus and
apply the same principles to the Earth thereby affirming a new way to
explain the seasons.
