Modern agreement with the study done by Eratosthenes in ancient Greece, requires the a priori premise that the earth is spherical and the sun’s rays are parallel.
.
To be accurate, what his proposition provides for modern times, objectively interpreted, is as follows:
GIVEN: EARTH IS SPHERICAL & SUN’S RAYS PARALLEL; ERGO: CIRcuмFERENCE OF EARTH = 25,000 MILES.
.
The argument flat-earthers make against it is, by replacing the “SPHERICAL” with “FLAT” and replacing “PARALLEL” with “DIVERGENT,” that 25,000 mile circuмference is no longer a valid conclusion!
.
For by using the same mathematics but inserting formulas with “flat” earth and “diverging” sun rays (IOW they deny that the sun’s rays are parallel!), the same results of different length shadows are obtained, when the sun is presumed to be about 3,000 (or 3,400) miles away, instead of 93 million.
.
Effectively, the essential proposition may be reduced to: "The sun’s rays are parallel."

The science of flat earth is only recently beginning to be understood. There are many divergent views when it comes to flat earthers but they only agree on one thing: earth is not a globe. The sun's rays don't reveal the circuмference of the earth. The so-called circuмference is provided by modern science and as such, with all the lies promoted by modern scientists, that also remains in question.

Yes, it is a popularity club founded on denial of the obvious, without any objective evidence.
It has nothing to do with what IS, but rather it's all about what "isn't."
It has a lot in common with the Tower of Babel: a lot of noise and confusion!
.
It's a rumor mill, basically, without any principles and without any positive foundation.
Flat-earthism denies reason and circles the wagons around a silly myth.
And your response to the OP is a case in point: off topic, and has nothing to do with Eratosthenes or his calculation.
Most forums that discuss such topics would have deleted your off-topic reply.

Denial of the obvious? Sounds like globers. It's obvious that water doesn't curve around the outside of a ball and stick to it. It is obvious that sea level does not mean the sea is curved. It is obvious that rain doesn't fall up on those at the bottom. It is obvious man is on a level playing field, not a spinning ball. It is obvious the Fathers of the Church tried to use Scripture to show earth is not a globe. It is obvious the history of the globe is consistently pagan. It is obvious Scripture describes a land mass that is not a globe, covered by an atmospheric dome and that vacuum of space cannot exist side by side with earth's atmosphere. It is obvious that earth is not a globe, and that globers rely on spin for their ridiculous stories. It is obvious the globe is a long term indoctrination foisted on the masses. It is obvious the Fathers of the Church spoke of the church and tabernacles as microcosms of earth and none of them are globes. It is obvious earth is not a globe.

Now HERE'S an oxymoron for you:

Science and "flat" earth are mutually exclusive, therefore, it will never be understood.

Repetition of "obvious" demonstrates obsequious nescience, obviously! So what else is new?

Science and flat earth are totally harmonious. Only false scientism doesn't work with flat earth.

See what happens when you're stuck in flat-earthdown-syndrome?

Science and "flat" earth are mutually exclusive, unless you're subject to "the syndrome."

Sorry, I misspelled flat-earthdom syndrome. My bad :)

False. Flat earthers use the 25,000 mile circuмference in all their calculations, repeatedly proving earth is not a globe.
