My wife and I were talking about exactly this the other night. We saw several satellites that night, being in a good dark star-gazing place. The only contact I had with flat-earthers gave me no insights. They dismiss out of hand very simple logical observations that make sense in a spherical world and not in a flat one. They just dismiss them. That's not argument, and it didn't help me at all. I kept my mind open to flat earth, because all hypotheses (spherical earth included) need to address competing hypotheses. But I haven't yet seen arguments remotely sufficient to change my mind. The sphere is a remarkably solid interpretation of what we witness every moment of every day. I'll keep listening, but until I hear something very different from what I have heard from the flat-earth types (something far more convincing), the earth is still an obloid sphere in space for me.
