It is true we can't directly measure one way speed of light when the light is aimed directly at us without clock synchronization. But we do have overwhelming evidence that one way speed of light is isotopic when the light is shining out from a cosmic event in every direction except pointed directly at us. This comes from observation of type II supernova. In the hundreds of thousands of years before going bang the supernova's progenitor star usually shed substantial amount of its outer layers in a series of minor cataclysms. This results in a Russian doll like layered expanding spherical shells of gas surrounding the progenitor star that we can observe in the form of planetary nebula. When the star does go supernova the massive pulse of light from the supernovae would reach out from the epicenter in all directions at speed of light, and successively hit each shell, heat them, and cause them to glow intensely. We can use just our own clock to see exactly how long after the instant of supernova explosion the outward racing light from the nova hits each point in each shell surrounding the supernova. And you know what, each point on each in the cross section of the spherical shell light up at almost the same time, to within the difference fully accountable by the know minor deviation from perfect sphericality of the gas shells. The different shells light up in succession precisely according to the shell's radius and this distance from the origin of supernova light at its center. You know what, the results show the successive shells become excited by the light from supernova at precisely the times predicted if light from supernova moves out in every direction at exactly the know universal speed of light C.

So this tells us with certainty without any spectacular special pleading assumption that light emanating from cosmic sources travels isotropically at C without requiring any special, tailored synchronization between the clocks at each point on each shell. Only one master clock at the observer is necessary.

Wordork is thus stripped to his disgusting nakedness, his argument reduced to not just special pleading, but special exemptions to special pleading. Yes, light is instantaneous except when we observe its progress from supernova, but its finite isotropy in this case applies except only in just those instances where its isotropy would show the bible to be bulkshit and wordork to be a sack of shit.

All this convolution, and more, just so he can cling to the only reason he ever advanced for believing the bible, because it is "consistent".

Yet anything can be made to seem consistent special if the fool is willing to special plead on the fly to avoid each and every inconsistency. So we must conclude he does not cling to the bible because it is consistent. He clings to the bible because he is diseased, and "bible is most consistent" is just an intro to the special pleading to make himself seem, to himself only, to be less diseased.
