Ancient Greeks were able to determine that the surface of the Earth is curved by observing same-time shadow differences in like structures spanning their geography.
That same crude test can be extrapolated to hemispheres to illustrate day/night simultaneously.
Were the Greeks right? I think so, although I'd be open to a refutation that didn't deny the empirical.
Dude what? The earth is round based on this? How do YOU know its round.
Where do flat earthers suggest is the alternative course of the sun and moon? How do they move around the disk of the Earth?
We are trying to prove round earth. Not disprove flat earth.
Of course, given we have been lied to for centuries there are many questions.
My eyes tell me the earth is flat. So that's the starting point. Need to be convinced otherwise.
Just because my grade 2 teacher, NASA, MSM, Elon say otherwise doesn't make it so.
Sure.
I guess I lean towards disregarding those on the left's position that math is racist as well as those on the right's position that math is a psyop.
The calculations for determining shadow height differences at different spots on Earth for a given time (sun position) are relatively straightforward.
We have the technology now to verify those calculations simultaneously, which should be enough to deduce whether the Earth is more spherical vs disk shaped.
To be honest, I haven't look deeply into flat earth's hypothesis, but never ran into serious defenders of the idea before #Bitcoin Twitter.
If the sun was local wouldn't the shadow also be different at different places?
What do you mean local here?
I suppose much depends on the agreed/assumed size, energy, and distance of the sun.
If the sun was smaller than the moon and just miles above the disk-like Earth, then yes, shadows would vary regardless of position.
That still requires a hypothesis as to how parts of the disk were day vs night, and the path the sun and moon would follow to facilitate this.
It's a good meme. My thoughts below.

Local meaning a few thousand miles above. Maybe the earth is electromagnetic and the sun and moon move like the hands of a clock.
Is the sun round?
Don't know
I'll try and find out what flat earth theory suggests in this case. I agree that if we are fundamentally wrong about things like the sun's size, shape, and distance, then alot of theories about the known universe are no longer valid.
Go out tonight and watch the moon. You can see with your own eyes that it is shaped as a sphere. Why would the earth be formed in any other way than this? So fucking stupid.
