Please provide this evidence you claim exists.
The fact that the motion of stars indicates its spin.
...that different stars are observed from the southern hemisphere.
...that the differing positions of planets in the sky demonstrates our (and their) revolutions about the sun.
...that lunar eclipses occur.
...that our most accurate maps are spherical.
...that we see things drop over the horizon (including the sun).
...that we have pictures of it from space.
...oh yeah, and that the Earth's magnetic field DOES NOT WORK in the way we would expect for a flat planet--only for a round one.
That's all I can come up with off the top of my head. Now where's the evidence that the Earth is flat aside from the already-shown-to-be-invalid "it looks flat to me?"
