The stick experiment (your way) would work only for two locations. For all other locations, it would give the wrong answer. All other locations would have parallel lines of sight to the sun, possible only on a spherical Earth. I mean, this has been figured out by astronomers making measurements. Why don't you do the math instead of the arm-wave?
