On the first day of spring and fall the flat earth crowd believes the sun travels over the equator. The heading of the sunrise at Portland, Maine is due East. The simultaneous heading of the sunrise in Santiago, Chile which is South of the equator (but also at 70 West longitude) is also due East. These facts are indisputable. So either we have two suns or the sun is millions of miles away. If the sun is far away then a flat earth would have sunshine 24 hours a day.
