You didn't highlight anything quite honestly. you quoted him out of context and gave no refutation. You basically just said this an acceptable fact anyone questioning it is wrong by default. Nothing in science is ever settled , everything is a theory and until better theory comes along.
Wrong, Apparently we can see a horizon 5 miles a way , so in 5 miles its a enough carvature to see a ship disappear. Yet we cannot detect that curve over 10 miles? For we have uninterrupted 5 miles to our right and 5 miles to our left. We should see enough curvature to hide 2 ships, but we don't. So if we can see a curve over 5 miles , why cant we see one over 10 miles?
Why haven't we ever seen curved water before? If the earth bends water in to a sphere around it and it was to freeze suddenly we should see a hump in the water, shouldn't we? So why is that when Lake Baikal in Siberia freezes over it is one of the flatest places on earth? Despite being 395 miles long and 49 miles wide. There should be hump in the middle of it being nearly 20 miles high. Why haven't we ever seen curved water?
No calling the scientist retard is an insult ,saaxiib.
Because when a person is on an object that's exponentially larger than itself, that object will appear to the person as a wide flat expanse, no matter what it's true shape. Saaxib this isn't even up for debate - because by saying there's a debate you're lending respect to the other side and I'm sorry, but it's hard for me to take a Flat earth believer seriously.
