It is believed that those who embraced a sphere Earth before the modern era were smart and those who embraced a Flat Earth were ignorant.
Sure, "It is believed that those who embraced a sphere Earth before the modern era were smart" because the based there belief on evidence accumulated over centuries.
But who claimed that, "those who embraced a Flat Earth were ignorant". The few "who embraced a Flat Earth" mainly "embraced a Flat Earth" for religious reasons and not evidence.
Yet no one can provide the hard evidence of sphere Earth used at that time to prove to the people Earth is a sphere. Why?
That is simply a silly expectation because all we have is what survives of what was written then.
There is, however, much written by Ptolemy, a Greco-Roman, The Venerable Bede, English, Al Biruni, of Persia, and Johannes de Sacrobosco, of France.
But I'm not going to waste my time detailing all of that just to have you ignore as you do with everything else.
So, who are the real ignorant and persuasive group? Are they the ones who rejected the idea on grounds of no real evidence or those who accepted it as indoctrination without real evidence?
The ignorant ones are you flat earthers who reject the Globe with no real evidence!
And most flat earthers accepted the flat earth by what amounts to indoctrination from sources like far earth YouTube videos that show no real evidence!
Yes, the Globe theory began through ignorance and indoctrination.
That is a total fabrication and you have no credible basis for such a claim!
There is a tremendous amount of evidence that, before around 600 BC, the earth was considered flat but with like semblance to the current ludicrous flat earth model!
The change to seeing the earth as a Globe came as people travelled further and gathered evidence that did not fit their earlier beliefs.
No one in their right mind can look at a horizon like this (below) and think Earth is a sphere.
I've already written about that photograph! It has nothing that indicates that the earth might not be a Globe.
