See, my main problem with this is that it is entirely a circular argument. You can't prove that the Earth is flat- or come up with evidence to support the Earth being flat- by starting "the Earth is flat, therefore..."; you can't support a conclusion using that very same conclusion as a premise. And then of course, the "it looks flat" is just plain ridiculous. I'm hoping I can find someone who can provide me at least a slightly more compelling case. A man can dream!
I'll check out the Experimental Evidence page, though. Perhaps that will be more enlightening.
