The Earth polar coordinates turn in a circle to the central Sun and in
less than two weeks will turn through the circle of illumination as it
has done two for every orbit over the billions of years it has been in
existence -

Apart from the degree of inclination,the planet Uranus is doing the
exact same thing -

I don't know why people do not see why the Earth has a largely
equatorial climate when all the information is put together and
especially the simple imitation analogy which explains two separate
axis for two simple motions,one daily rotational and the other
orbital,for without this information it is impossible to discuss
climate or weather.

A society without astronomy has really nothing to say.
