In addition, this "you have no model" comes from individuals who are clearly ignorant of the fact that there is a working model out there that explains many/most of the phenomena we see. They're ignorant because they never studied the question nor even gave it the time of day, so to speak. It's obvious they don't know what the model is because they never looked at it, and therefore claim that their ignorance means there isn't one. FE model explains many/most of the phenomena we see, and hasn't been falsified, unlike the globe model, which has. So the working FE model is closer to the truth that the globe model. Certainly FEs don't have the scientific apparatus to investigate all the details of the model, but it works conceptually and is in the state of hypothesis (you know, of the old "scientific" method, which these adherents of scientism evidently know very little about), and is subject to amendment or actually falsification. If it's been falsified to the point that no adjustments to the model can salvage it, then it will be time to seek another one. Until its falsification, however, as more data and observations come in, the model will be continually refined. This has happened even with the solar system cosmology. Initially the orbits of the planets were ovals, then they became ellipses. Initially everything orbited the sun, then later, after gravity had been "invented", everything orbited the center of mass. In fact, until Newton invented gravity, they had absolutely no idea how the planets revolved around the sun. Many heliocentric models had these layers of "solid spheres" around the sun. First the sun was 1 million miles away, then 5, then 7, then 10, then 23, then 30, then 50, then 70, then 100, and now 93 million miles away (with each distance also affecting its size). Based on the "logic" of the globers, heliocentrism should have been invalidated every time they got one of these details wrong.
Then, of course, for those of us who actually have faith in the inerrancy of Sacred Scripture, the FE model is clearly back by the Sacred Scriptures, written by the Holy Ghost, wherein the cosmos is describe in a way that's consistent with the FE model and which falsifies the globe model, despite the Modernistic explaining-away that needs to be done, turning everything into metaphors, non-scientific language, and then finally going to the well of "Scripture didn't intend to teach about science" Modernist maxim.
