q.v. Post 140 please --- that says it all. It's a perfect illustration of how "science" and Scripture clash
You asked why I didn't say that scientists taught ancient people that the Earth was flat. I told you that I didn't say that because that's not true. Tell me how post 140 interacts with that, because as best I can tell the two are almost entirely unrelated.
You say those who once believed the earth was flat.
How did they come to believe that, when Isaiah and David taught otherwise?
TO answer your first question: Most likely because it appears flat when you stand on it.
I don't believe that you can support that either Isaiag or David thought that the Earth was a shpereoid.
I'll tell you. Some rebellious Bibliphobe decided that his "science" and "observations" were more authoritative than Scripture, and started teaching that heresy as 'science'. Then people, CONTRARY TO SCRIPTURE, started believing it.
That fails to explain why the belief was so widespread (including times predating a bible to be phobic of and areas where there was not a bible to be phobic of). It completely fails Occam's razor, and you cannot offer even cursiory support.
Then comes someone like Christopher Columbus, who knows better because he believes the Bible, not 'science' ... and basically proves 'science' wrong and the Bible correct.
Actually, scientific methods established not only the shape of the earth, but the size, about 2000 years before Colombus.
But what do the 'scientists' do? They just say, "Oops, now we have more evidence" and they readjust their data to ... guess what? ... coincide with the Bible!
Scientists do adjust their hypothesis and theorum and laws and facts when they have more data; but flat Earth was never a scientifically established position, nor is it BIblical (the Earth is the result of the waters below seperating and allowing ground to appear between).
