The Earth is nearly a sphere but not exactly, and its orbit round the sun is nearly
a circle but not exactly. The differences are easily measurable.
Regarding the question's second erroneous hypothesis, ball bearings, flywheels,
the evacuated chambers of particle accelerators, the figure of the primary mirrors
in Schmidt cameras, and the arc of the rainbow, are each as perfect a circle as it's
possible to measure.

What is the name of longitude 66.5 degrees south of the equator called?

Why is the equator the only parallel that is a great circle?
The equator is the only parallel that is a great circle because it is centered on the Earth's axis of rotation. This means that it divides the Earth into two equal hemispheres and its circumference is the maximum possible for a circle on the Earth's surface. Other parallels are smaller circles and not great circles.

How many miles down is the Arctic Circle and is there sand where animals could have once roamed the earth?
1) The Arctic circle is an IMAGINARY line of latitude at 66° 33′ North. - so thinking of it as 'miles down' is wrong. 2) There are plenty of examples in the Earth's fossil record of ancient animals walking across sand - ( this is of cause nothing to do with the Arctic Circle).
