you are splitting hairs
the tilt is very close to 23.4, and 90-23.4 is still 66.6. and the sun still behaves in the same manner. this does not destroy the theory.
the ancients used the number because of this, it's the magic square of the sun etc. this is all over the world from china to iran to wherever. it was common knowledge in the times.
>The Earth's axial tilt is approximately 23.4 degrees, which is a critical factor in the planet's seasonal variations.
> This tilt is also referred to as the obliquity of the Earth and is measured from the imaginary line that runs perpendicular to the Earth's ecliptic plane.
>The exact value of the axial tilt is currently about 23.44°, and it is gradually decreasing over time.
> The tilt causes the seasons by affecting the amount of sunlight different parts of the Earth receive throughout the year.
>The difference between the Winter and Summer solstice is effectively double the axial tilt, at 46.8 degrees.
