I don’t think it’s as simple as that. Everything is ratios. Yes, the current numbers provided can justify a spherical earth. But I could also fill in my own, properly ratioed numbers that could justify another’s belief in a flat earth. In all honesty, I’m probably more like you. I don’t claim to know what the world looks like because I’ve never been far enough away to see it in comparison. But I used to believe it was spherical. I no longer hold that particular belief.
