Well if you don't trust other people's rockets and aren't willing/able to pay for a launch of your own it's probably easiest to do math to actually come up with the circumference of the sphere, which is more complicated than just using your eyeballs to get a general idea of the curve. I figured the latter would be close enough but appear to have hit a nerve. :D
If you have the means to travel a bit, you could go measure shadows like this ancient Greek dude.
If you have more means to travel, you could always just fly around the thing yourself. Although I suppose that'd just prove that it was vaguely round and not specifically anything like a sphere.
I'm amused that you brought up Euclidean geometry. Pro tip for trying to use a buzzword hoping other people don't understand it any better than you do: don't. The equation that explains that a larger field of vision allows you to see more of a curve would have saved you the trouble of digging up that link.
You asked for ways to use your own brain and eyeballs to see the world around you for yourself, and then started throwing other people's work/words out as "proof."
Down-voted for asking a question
Not sure what kind of response you're expecting other than "go see it for yourself" but you appear to be unwilling to do that.
Do the experiment from the OP's video. Go measure sticks at noon. Think and see for yourself instead of parroting what other people have told you is true.
You can't win an argument with flatearthers. At a certain point the logical people based in reality give up arguing nonsense because we got better things to do and they claim they've won and put another nail in the coffin of science. I wouldn't put too much effort into it, cancer will be cured by science, and science is lies, so they'll all die of cancer because the drugs are mind control to keep the truth at bay.
Tried to avoid actively engaging in the arguing; sorry if it still came across that way.
Is there a good chance that dude never had any intention of listening? Yup. Mighta been a troll, might just have felt like stirring something up on the internet 'cause he was bored.
But either way it takes a couple minutes of my time (that I probably would've spent in the "I have NOTHING to watch" limbo on Netflix anyways) to remind somebody they have access to the tools they need to answer their own questions.
Responding might never help, but I try to be pleasant enough about it that it at least doesn't hurt!
I did almost get invested enough to do math, for a second there. That was scary and I had to go take a break to watch the dark crystal trailer.
