Too many... or not enough... I'd kind of rather people are smart enough to figure that out, and if that means posting about it then I'd rather than an alternative scenario where they *don't* think so don't realise the numbers aren't legitimate.
I absolutely have no idea how anyone could ever in our modern times subscribe the the idea that our world is flat. I believe in some pretty out there things, but even the ancient Greeks figured out the world was round just using some simple math.
