Yes, you cannot do the math to show there is a curve. It's easy. But it would just be math. The burden of proof lies on you, because I have never seen the globe. Or any curve. I see flat horizons, even as I go up, I don't feel movement when I should. You've just been brain washed to believe you just can't feel it. You never honestly took into consideration why a hot air balloon doesn't eventually separate from the speed of the ground below.

You trust, you believe, and I'm probably way better at math and physics than you, but we don't need that to know you base your entire world view on institutionalized knowledge.

You prove there is a curve. That's the claim. Because all I see is flat. You can't prove it. Because it's a belief
