I'm actually here because it's virtually insurmountable. I've always loved debating challenges, and being told '90 Percent Of The Evidence You Bring Is Inadmissable' provides one hell of a challenge.
Still, says something about the human race, eh? Even after we develop the ability to go into space and get the answer...
If Round Earth supporters went into space and came back and announced the world was round, 'conspiracy' would be announced. If Flat Earth supporters went up into space and came back saying the Earth is flat, same thing will happen. In the end, it all boils down to belief, and no amount of evidence will ever convince everyone.
