No, the genetic fallacy is not germane here. You are conflating the derivation of knowledge and direct knowing, which are distinct. You conflate the ingredients on the back of the label for the taste of the sweets in the pouch. The taste of sweetness is what I am indicating, not the list of ingredients. Also, you are suggesting that there is an impersonal objective spacetime irrespective of observer which is false. There is a generalized case that works for the figures projected for measuring the distances to solar bodies from other solar bodies. But you are basing your analysis on the hidden assumption that the material reality is first. This is an unchallenged assumption in modern science which leads you astray.
