A-if the earth is always at 23.5 degrees and always pointing at polaris, then that means that polaris is also moving
--
B-if the earth is always at 23.5 degrees and not always pointing at polaris, then that means that the earth is moving but polaris is not moving
--
can all you round earthers pick one of the above A or B and tell us which one y'all believe in
--
can't have round earthers with 2 different theories
There are not two different theories. There is one theory, which people agree on. The thing is, people often state "facts" which are not exactly true, but very close to true, to a very good approximation. In fact, Erasmus is doing the same thing right now. Polaris is moving, as are all of the stars in the milky way galaxy, and the galaxy itself is moving away from all other galaxies. Also, the north pole is not always pointing in the same direction. There is a small wobble in the earth's spin, which causes the axis to move over time. Several thousand years from now, polaris will no longer be the north star, and another star will. Hence Erasmus comment of "this one, approximately."
The problem is that stating precisely what is going on in a given situation with meticulous detail requires, well, meticulous detail, most of which is irrelevent to the explanation of the phenomena in question. So when round-earthers state that the north pole always points at polaris, they aren't lying, and they aren't wrong, they're just not elaborating on all of the irrelevant details, and stating a "fact" which is not precisely true, but true to a very high order of precision.
