I don't understand the 'jigsaw puzzle' bit at all.

Do you understand the 'political coincidence'? I've described it repeatedly at length.

I don't understand the importance you seem to ascribe to it. Peirce was working on his own in his eccentric way, some committee or other decided to place the prime meridian in London. I don't understand why there should be any relationship between these events.

my favorite part of these flat earth maps is how latitude and longitude apparently have no real meaning and are treated as just lines on a piece of paper. 

Are you suggesting there are large blue lines painted across the ocean? Or are they just lines on a piece of paper?

Are they real or are they man-made is essentially the question.

I think the answer is: "a bit of both".

But, yes, lines of latitude do represent something tangible which relates to reality, so they can't just be added willy nilly to a flat earth map.
