For me, the curvature is the big issue. Clearly, we can see objects farther than just 6 miles or whatever. Things that according to the trig, should be hidden by the curvature. This is common across the world and I havent seen a reasonable explanation from globe earthers.
I am not saying the earth is flat, maybe the earth is like 1000x bigger than they say so the curvature is off.
But this is something normal people in everyday life can discuss.
I think there was a video of being able to see across one of the great lakes. That shouldn't be possible.
For an example from my personal experience I can see a city thats 20-30 miles away. Laying down on the beach doesn't really change how much I can see so I'm not gonna bother with the eyesight level differences that the second calculator has, I'm gonna use the first.
So if I plug a number into this calculator, it spits out the amount an object should be hidden... From the bottom up according to the ball model.
20 miles: 0.05052 miles = 266.75 feet
30 miles: 0.11367 miles = 600.19 feet
So that means I shouldn't be able to see the bottom 266 feet of whatever is 20 miles away. I'm not sure exactly where they're getting that, as I can still see all of the beach on that opposing shore. Nothing at all looks like its hidden.
My city is 500 meters above sea-level, so it shows the horizon as 50mi away.
Thats....... not how that works. If you put in 500 meters for the altitude its like saying you're standing on a 500 meter tall building, not that the balls radius is 500m larger. The horizon is 50 miles away because you're up so high in relation to the radius of the earth. If you scroll down on that page they go over exactly all of the variables of the equation.
What's your reasoning for not seeing objects much further? Why can't I see the Alps from where I am?
Humidity. Eventually theres too much water to see through to get a clear picture of anything. This video goes over this concept in a little more depth.

Not OP but I can reply about earth curvature calculations.
You can do a search and find earth curvature calculators such as these.

This is not found, and the link including it fails. The site itself is up, but that specific element has been removed or broken.
Works for me. Just google “earth curvature calculator” there’s more of them
