Why would the sun be static under one assumption and then not under the other? The question is a simple application either model: is the sun moving across the sky or not? It wouldn’t support either model to take video and have it appear stationary. But obviously if you record for long enough it will move… so how does this apply in any way?

My proof: take a video of a blade of grass. Is it growing or stationary? Now do it over a few weeks. What’s the difference?
