Insulting yourselves or helping humanity

I am certain that you all can explain the graphic in terms of
variations in axial tilt/Equatorial orientation to the Sun because you
are indoctrinated like so many before you.It is time to come to
something astronomically better.

An intelligent person would cut axial orientation loose and concentrate
on orbital motion and the changes it brings to the orbital orientation
of the Earth against an axial orientation that is more or less
fixed.The first thing to do is not give into the temptation of framing
axial rotation to the distant Sun and to shift the orbital perspective
away from the Equator/orbital plane and just consider the orientation
which at present is almost aligned with terrestial longitudes.

The choice of remaining to insult yourselves or to actually help
humanity is left to each individual here,there is nothing difficult
beyond the initial unfamiliarity with the actual working principles of
axial and orbital motions have independent motions and orientations and
applying what moves and what does not.
