For a range of reasons (discussed elsewhere).
Many of our observations in geology, such as plate tectonics, are not explained by a flat Earth.Ī spherical Earth is also a fundamental fact of navigation.Īnd of course we have many photographs of a spherical Earth from space. As other answers have indicated, very few flat-Earth proselytizers actually believe the Earth is flat. We now know that if the Earth were a flat disc instead of a sphere, gravity would also tend to pull people at the edges inwards towards the centre, not just down towards the surface-with all sorts of strange effects that we do not observe. The Greek mathematician Eratosthenes and the Roman-Greek-Egyptian mathematician Ptolemy were able to estimate the circumference of the Earth quite accurately, by measuring the angle of the sun in different places at the same time. Most people in England have either read, or heard, that Sir Isaac Newton's theory of gravitation was originated by his seeing an apple fall to the earth. Indeed people were able to demonstrate this in several ways more than two thousand years ago.Īristotle, for instance, observed that the Earth’s shadow on the moon during a lunar eclipse is always circular. Some Bible critics have claimed that Revelation 7:1 assumes a flat Earth since the verse refers to angels.
There are many ways to prove that the Earth is spherical. No, this false idea is not taught in Scripture.
