Number one, thank you for addressing this interesting topic of the flat earth. Secondly, the man you met, Mark Sargent, is NOT a member of The Flat Earth Society.  Thirdly, we don't live on a globe. Science and journalists everywhere who aren't exploring the true nature of our world and are still repeating things they've been taught instead of things they've tested for themselves, will be left in the dust, much like the faux footprints on the stage set where they filmed the moon landing. Do some real research. Check the web site http://stoplookthink.com/flat-earth/or watch a quick video called Flat Earth In 5 Minutes on YouTube. Mark Sargent's Flat Earth Clues is another great place to start on his YouTube channel Mark K. Sargent.
