Why do people have beliefs that are clearly ridiculous?

@SomeMichGuy The last few years? 🤨
The true shape of the Earth has been known for at least the last 2,500 years, if you think such a span of time is "just the last few years".

@Pambie You need to re-read what I wrote. You inverted the meaning.

@SomeMichGuy
Apart from literally, how else am I supposed to interpret that? The Earth being flat as a "generally-accepted proposition", hasn't been such for at least the last 2500 or so years. No one during Medieval times, for example, believed it, not even the scruffiest peasant, and yet now we have in the 21st century no less, a band of idiots who think their silly intuitions about the shape of the planet are actually correct.

@Pambie Really? You need to read all the words...

You seem to have missed the ending of "did":

(Emphasis, annotation, and phrase replacement added.)

So I said that our current flat-Earthers, the ones about whom you wrote, did NOT grow up with something.

What is that "something"?

<something> =
{ "the Earth is flat" being a generally-accepted proposition which was only changed in the last few years...}

They did NOT grow up with the notion of a flat Earth being newly/recently changed. You agree that this is ancient knowledge, so you have to agree that they did NOT grow up with the idea of a cherished belief being recently dashed.

I never said that a non-flat Earth is recent knowledge.

@SomeMichGuy What is your point here? Do you know how to make yourself clear? The fact is they're wrong.; the Earth is NOT flat.
