3,000 years ago the Bible said the world was round. It is very clear: Isaiah (40:22)
Actually atheists tried to ridicule religious people by CLAIMING religious people thought the world was flat, which was not true.
Well, actually the word circle means that Isaiah is implying that the world is a disc, not a globe, sphere, or orb. The belief that the world is a disc was common amongst the less advanced ancient civilisations, particularly those who like the Hebrews were not seafarers, and as I have already pointed out this belief can be derived from many more biblical verses than those that clearly indicate that the earth is a sphere (right now I cannot think of any that are clear that the earth is a globe, but maybe you'll find one so I won't assert that there are none)
It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers; who stretches out the heavens like a curtain, and spreads them out like a tent to dwell in
Sure sounds like God sitting above a disc to me, tell me, how does He spread out a tent over a sphere? The verse makes no sense if you think of the earth as a sphere, and plenty of sense if you think of it as a disc.
Actually atheists tried to ridicule religious people by CLAIMING religious people thought the world was flat, which was not true.
So I'm sure you'll be able to come up with an actual example of an atheist ridiculing religious people in that way in the last ten years... I've never come across an atheist ridiculing for that once.
The actual false claim I repeatedly come across from creationists in these threads is the one that "scientists" pre Columbus thought that the world was flat but Columbus proved them wrong. Maybe once a month I get that canard as a kind of "scientists don't know squat" post so I assume that it is on some creationist websites out there.
