how can i believe that the earth is flat? also i am seeing alot of theories about earth being round and me even thinking about this theory people look at me like i am crazy or have something going on in my head. i did see that you can't fly from australia- rio grande argentina when its just across the waters about 6000miles out and i know planes can fly further eg... Then Concorde stops flying. And now this. Singapore Airlines Flight 21 passenger.
 That will leave Qantas Flight 7, a Boeing 747 from Sydney to Dallas, atop the list of world's longest nonstops by distance, at 8,600 miles.
can someone shed some real light in my face please?
