ok so how did the ancient greeks and egyptians observe it

The Egyptians used a revision of the Eratosthenes experiment using obelisks at certain points and distances measured out. I say revision for lack of a better term, because to the best of my knowledge, they never met the man nor knew of his experiments

i just told u it works on a flat earth with a local sun same as a far sun on a sphere

They calculated the circumference of the earth, much like the prior experiment, reached the same number, and found a curve

ok

sounds legit

Shadow angles would be different on a flat earth with a close sun vs a spherical earth. The shadows angles would have a consistent relationship with distance, say, every x miles the sun angle changes by y degrees, while on a flat earth, the farther away from the sun you are, the more distance you have to travel in order to have the shadows increase length by a certain amount.
Basically, with two shadows, sphere and flat are the same, more than two, they are different.

The sun would also never set on the flat earth unless it went below it.

Huh

Lol

neil degrasse tyson said eratosthenes experiment would worl the same on a sphere earth with a far sun and a flat earth with a close sun

imma just take his word for it

Mike: I am a hollowed earther
Also mike: flat earth is a physically proven fact
🤔

that neil telling u how it is

thats

She said they did a revision of the eratosthenes experiment, meaning it's a different experiment

He literally said it doesn't work on a flat earth, lol

Three wells,

he said it works on a flat or sphere earth

earatosthenes only used 2 wells so

their was no 3 wells in his experiment

And the point is, with a third, flat earth fails.

are u sure

Yes

well maybe maybe not idk

i jsut know the 2 wells in 200 bc would work either way so

they werent sure back then

they didnt know

since it coulda been both

when did they do it with 3 wells ?

So?
It is 2019, we now know

no we dont lol

u think u knoipw

u just think u know

Yes, we do. We literally have sun angle data from all around the world.

We aren't primitive like the ancients, we know how the sun works

that is debateable

we know how the sun works

u are sure ?

Yes, in terms of its positioning around the world

i wish i could be as sure as u are in all this
