This thread is a cool example of
Poe's Law! I love it!
There are many evidences that the earth is in fact round - spherical in fact.
On a flat Earth, the constellations seen from North America would be the same ones seen from South America. They are not the same. Therefore the Earth is not flat.
A more specific version of the same argument is that the so-called "North Star" wouldn't be the "North Star" is would be the "Center Star" and there would be no such thing as the south celestial pole. Polaris and Sigma Octantis (the closest naked-eye star to the south celestial pole) are not the same thing.
Also, the Moon is not visible from the whole Earth at once and the tides that the Moon and Sun create happen in the predictable way they do because the Earth is round and not flat.
There are, in fact, dozens, perhaps hundreds of astronomical observations of a similar nature that could only occur if the Earth were spherical.
The Sun, Mercury, Venus, our Moon, Mars, several asteroids, Jupiter, Jupiter's Moons, Saturn, Saturn's Moons, Uranus, Uranus' Moons, Neptune, Neptune's Moon, Several "Centaurs" (Minor planets) including Pluto and it's moon ARE ALL SPHERES!!!! But the Earth is flat? Give me a break!
The shadows cast by sticks or buildings or flag poles or whatever are different for different latitudes. Given the distance of the Sun, this would not be so on a flat Earth. And if you wanted to say that the Sun was close enough to the Earth that objects closer to the edge of the flat Earth cast longer shadows, then it still doesn't work because the shadows that are actually cast bare no resemblence whatsoever to such a scenerio. The shadows cast on the Earth are precisely what they should be if the Earth was a sphere. In fact, this shadow discrepancy was how the circumferance of the Earth was first calculated and with surprising accuracy given the technology at the time the measurement was performed.
As has already been pointed out in this thread, you can see further from a higher perspective. This would not occur on a flat Earth. No telescope, no matter how powerful, can see past the horizon but the horizon gets measurably further away with an increase in altitude. And guess what, the measurements of this effects are perfectly consistent with a spherical Earth! Imagine that!
Similarly, the existence of time zones is proof that the Earth cannot be flat.
Air planes fly in the wrong direction if the Earth is flat and every airline company in the world is intentionally wasting millions of dollars a year in fuel costs, doing there part, I suppose, in the conspiracy to convince the hoy-poloy that the Earth is round. A flight from Los Angeles to London, for example, doesn't fly in a direction that would make any sense whatsoever if the Earth were flat. (See picture below.) They do, however, fly in what are called orthodromic courses. An orthodrome is the shortest distance between two point ON A SPHERE!

And one of my very favorite arguments has to do with the center of gravity of the Earth. If the earth were flat, the closer you got to the edge of the Earth, the further away and the further behind you the center of gravity would get. It would feel like you were loosing weight and like the incline of the Earth was getting steaper and steaper the closer you got to the edge. If the Earth were flat, it would feel like we lived on the inside of a bowl and things would appear to fall sideways to a greater and greater degree as you got further from the center of the Earth. The fact the things not only fall straight down in both England and in Australia but that they do so at exactly the same rate and that a 16 pound bowling ball weighs 16 lbs in both places are all consistent with a shperical Earth and not a flat Earth.
Now if you're a flat Earther then you've got answers to all this and to whatever else anyone might bring up. Here's a great video that discusses what's really happening with this whole debate and with this specific thread....
