I meant that back when the meter was calibrated for the first time, they weren't able to measure the Earth that accurately, and so the official meter model was a little bit off from the true 1/10,000,000. Later improvements to the SI system defined the meter more accurately, but used the old meter model as the target length rather than obsolete everyone's existing rulers and break the compatibility of items built to standard measurements.
What do you mean? Flat earth is the most impossible conspiracy theory I've ever seen. There are so many good arguments against flat earth, including the WHY of it. But I'm sure you've heard that stuff before...
Ancient Egyptians in the time the pyramids were built did think the Earth was flat though and had no idea about latitudes, let alone a way to measure them to multiple decimal points. It wasn't until the Hellenistic period (still B.C., but much later) that the Egyptians became aware that the Earth is round.

What about "flat-earth"-theory? It cannot be proven nor denied...
