Uh, what? They knew the earth was a sphere:https://en.wikipedia.org/wiki/Eratosthenes#Measurement_of_th...
That's like saying that the world was flat before they could prove that it is round.
Please respond to the point about the earth being round.
"When people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."
Asimov wrote an excellent piece on this - The Relativity of Wrong: http://chem.tufts.edu/answersinscience/relativityofwrong.htmThe Earth isn't flat, but it certainly approximates being flat for small measurements of its surface (such as those early civilizations would've been able to make).
Wait, I thought earth was flat?
This is such a common trope. Erasthenes observed the Earth must be round using shadows over 2 thousand years ago. There was never an intellectual controversy about it before internet dupes fell for an obvious prank.

There are people who question that the Earth is a sphere.
The earth being round and its size is demonstrable without a rocket ship (and was demonstrated a couple millennia before anyone fired a rocket into space.[0])But, in any case, even ignoring that, the analogy was inapt.[0] https://en.m.wikipedia.org/wiki/Eratosthenes
