>> If you ask any scientist from before the times of Copernicus in the 1500s – they’ll tell you simply that the sun goes around the earth.
this is strictly not true. Several Greeks – Aristarchus, prob most famous – considered Earth moving around the sun. This was soon post-Alexander times; septuaginta. Others, like Archimedes, quote this and disagree. Seems like biggest arguments for Earth being in the center for the Greeks was lack of star parallax: were the Earth moving, then there will be changes in how we see (stationary) stars. They did not appreciate how far stars are.
As to Rambam, I don’t think he would hold by theories of his time now, he would probably have no problem accepting modern physics, so quoting him proves nothing.
