Definitely the earth is not flat but spherical in shape, sunset and sunrise, different time zones, rotation of the earth round the sun all bear to that
1. The reflection on the ocean during sunset/sunrise proves the water and hence the Earth is flat. I've also seen video of the sun setting and it being pulled back into full elevated view above the horizon with a zoom lens.
2. Time zones certainly don't prove the earth is a sphere, this doesn't make sense at all how is this proof? Perspective and the limiting effects of the atmosphere result in day/night and the timezones.
3. The earth is motionless and there are multiple established scientific experiments to prove it such as Airy's Experiment that failed to detect any motion and the Michelson & Morley experiment. Anybody with a precision gyroscope such as the one included in an Apple iPhone or Samsung Galaxy can prove for themselves that the Earth doesn't move.
All it takes is a little bit of critical thinking in regards to the available facts to see that the Earth is in fact a flat motionless plane.
