Arguments against a flat earth theory.

I keep seeing posts on Facebook about the earth being flat. So I thought for a few minutes and posted this…. . If the earth was flat the sun would set AT THE SAME TIME EVERYWHERE. There would be no time zones. New years eve would be celebrated at the same time everywhere. Clocks would all be set to the same time. If you live in a big country like America the sun would rise and set at the same time, so you wouldn’t need Eastern standard time and pacific time or whatever it’s called. THERE WOULD BE NO SEASONS, AND THE TEMPERATURE WOULD BE THE SAME ALL OVER THE WORLD. If the Earth is a globe and tipped you get seasons. If it’s a globe and not tipped, no seasons, flat earth? No seasons, no gradient in temperature. And the sun would rise and set at exactly the same time every day… Sorry rant over.
