I have an sincere request (not being snarky at all). Please visualize this related list of items.
Imagine standing about a football field length away from the Sears tower (I'm older - I still call it the Sears tower) in Chicago and tilting your head to look at the top. Now imagine how incredibly tall it would look with 10 Sears towers stacked on top of each other. Asking to really let that sink in.
According to a Google search you can't begin to visually detect the curve of the earth until you reach 35,000 (I've seen estimates as high as 100,000 feet, but I'm going with 35,000 because it is actually less favorable to my argument). At 35,000 feet the visible horizon ends at 229 miles.
Now imagine standing on a beach with a straight and long coastline (at least 229 miles). Assuming an eye height of 6 feet (that's taller than average, but I'm trying to be conservative with my argument). An object 229 miles away would have to be taller than 23 stacked Sears towers before you could begin to see any of it.
With a globe earth there is no honest debate against any of these statistics (oblate spheroid can't possibly have a material impact - remember the Big Blue Marble is a real photograph where no "oblateness" can be detected).
Your side is asking me to believe that the earth's curve CAN'T EVEN BEGIN to be visually detected until a height of at least 35,000 feet is reached. However, at that height's horizon an object would have to be over 34,000 feet high before someone with an eye height of 6 feet could even begin to see the top of it just starting to peek over the curve obstructing its view. Being straight with you I think that's ridiculous.
Extremely high optical zoom cameras like the Nikon P900 & P1000 have demonstrated impossibly visible hidden targets across a body of water over and over again (it's not even close to possible on the globe). Big tech does its best to censor these but they can be found. It's no coincidence that big tech does not censor, but instead their algorithms make it very easy to find the "Flat Earth Meetup People" or "Flat Earth Bongo Drum Beating / Spirit Bead Wearing Nuts".
All that stats I quoted can be confirmed here ...

This is why anyone trying to convert a "flat earther" back to globe earth is unlikely to ever have any success with "look over here" arguments quoting all kinds of impressive scientific sounding words. They may have success convincing fence sitters to stay on the fence or move to the globe. The only way to have any chance of changing the mind of a grounded flat earther is to beyond any doubt disprove the impossible visually confirmed "hidden targets" that have been demonstrated over and over again. Flat Earth debunkers IMO tend to stay away from that for good reason because I suspect they know it can't honestly be done.
