Neither of these quotes say "invisible magic subduction zones." Therefore, you are still a liar. QED.
Since Carey's work has since been discredited by modern science, that quote is dismissed as irrelevant. Since even you could have written the WikiPedia article, it can be dismissed as irrelevant.
What remains is a single quote-mined comment by a professor who is using the context that his research is worth funding and his classes are worth attending. No where in his work does he indicate that he has empirically tested all planets in the universe or even the solar system.
We are the only planet that is shown to have complex forms of life (so far, any life at all). Yet this doesn't imply that life isn't waiting to be discovered elsewhere in the universe and even our own solar system.
What the educated geologist actually understands is that Earth sits in the Goldilocks zone for temperature and climate. By mere chance, we have the ingredients necessary for just the right amount of equilibrium just the right amount of entropy is negated to allow for life. Plate tectonics appears to be a symptom of that situation.
But, assuming that you're logical fallacy (applying a poor analogy) that since we haven't seen plate tectonics elsewhere (other than Earth) is true, it doesn't imply that plate tectonics, therefore, doesn't exist. Only the most ignorant and undereducated would dare take such a stance.
Instead, plate tectonics is an empirically verified phenomenon. It does happen, regardless of you head in the sand and denial of it as a phenomenon. One can say there's no gravity all one wants, but one will remain on the ground with the rest of us. Your denial is just as silly and undereducated as denial of gravity.
No planetary scientist or geologist is claiming that plate tectonics will not be discovered elsewhere in the universe. Indeed, there is recent indication that plate tectonics may have been present on Mars. I'll be away for possibly two days. When I return, perhaps I'll describe these recent discoveries and cite the sources they are derrived from.
To sum: not a single quote you provided said "invisible magic subduction zones." You are a liar.
