It would seem that if distance alone explained the aeronautical observations, the sun couldn't be more than 100 - 500 miles away, at most. 0.2%, though granted several times more than if the sun is 93M miles, is still too insignificant to explain the observations. There must be other explanations. I find it hard to believe that the sun is 93M miles away. But that still doesn't convince me that the earth is flat.
I've seen various figures given in flat earth literature, e.g. 1,000 mi, 3,000 miles, even 300 miles.
One thing I know for certain is the diameter of the moon: 70-100 miles.
This is a FACT and can be observed scientifically from the solar eclipses.
Shadows only lengthen, they do NOT increase is size (width).
