I find an argument is only worth having if the opposition is coherent, informed and at least show that they practice what they preach.
If you are a sailor out beyond the site of land you will look for a method of fixing your position from what is available, which pretty much means the sky. If you have ever looked up at the sky you will notice that the nearer you look to the horizon the more the stars move, both through the night and the year, in the northern hemisphere looking up to the north the constellation Ursa major pivots around Polaris, using Rounders analogy of the turntable there will always be one part of the sky that remains stationary, in the north there is a star there, in the south there isn’t, so a “lucky thing” in only 50% of the planet, not much room for a conspiracy there then.
Incidentally, in 320 BC the Greek navigator Pytheas described the celestial pole devoid of stars.
As the stars are not fixed, they move position, Polaris won't be there in a couple of thousand years.
