Stephen Hawking presents Aristotle's thoughts on a round Earth.

As long ago as 340 BC the Greek philosopher Aristotle, in his book On the Heavens, was able to put forward
two good arguments for believing that the earth was a round sphere rather than a flat plate. First, he realized
that eclipses of the moon were caused by the earth coming between the sun and the moon. The earth’s
shadow on the moon was always round, which would be true only if the earth was spherical. If the earth had
been a flat disk, the shadow would have been elongated and elliptical, unless the eclipse always occurred at a
time when the sun was directly under the center of the disk. Second, the Greeks knew from their travels that
the North Star appeared lower in the sky when viewed in the south than it did in more northerly regions. (Since
the North Star lies over the North Pole, it appears to be directly above an observer at the North Pole, but to
someone looking from the equator, it appears to lie just at the horizon. From the difference in the apparent
position of the North Star in Egypt and Greece, Aristotle even quoted an estimate that the distance around the
earth was 400,000 stadia. It is not known exactly what length a stadium was, but it may have been about 200
yards, which would make Aristotle’s estimate about twice the currently accepted figure. The Greeks even had a
third argument that the earth must be round, for why else does one first see the sails of a ship coming over the
horizon, and only later see the hull?

-Stephen Hawking, -A Brief History of Time

In the FAQ, it states using information gathered by our senses to determine the curvature of the earth, and this information is clearly gathered by the senses. Test the Eclipse theory using a lamp, a sphere, and a plate, then next time there is an eclipse, go outside and look at the moon. If the shadow on the moon will be round, as opposed to the shadow on the sphere used in the experiment, which will be elliptical. This disproves FE theory definitively.

The pole star is a bit of a red herring. It's all about perspective: as you get further from the star, it gets lower, because it's further away from you, so it's closer to the vanishing point.

Not if you understand the basic concepts of latitude and trigonometry.
Science is what happens when preconception meets verification.

Besides, perhaps FET is a conspiracy too.
