1. The firmament contains the atmosphere with the sun and moon being close to earth. EXAMPLE: Crepuscular sun rays prove the sun is close.
2. Antarctica is a frozen circumference that contains the oceans, 1800's maps show this. What is beyond Antarctica is a mystery.
3. Explorers can't survive -100 F and 80 mph winds to explore deep into Antarctica.
4. The sun is close to the earth and reaches a vanishing point. There is also a time lapse video of the midnight sun in the video above. Stupid videos? Oh, you mean those provided by NASA that you worship? Yeah those are child like in their fakery.
5. Underneath? WATER. Above? WATER.
6. Weather balloons you mean? Satellites LOL !!! NASA uses a lot of helium!
7. My opinions come from factual evidence. They are the results of real scientific experiments. EXAMPLE: Lighthouses depending on how tall can be seen 30-60 miles out at sea. When you do the math of the earth's supposed curvature they should be thousands of feet below the horizon and invisible. OR The entire Chicago skyline can be seen across Lake Michigan. Where is the curve? The gradient of rivers can be measured and it doesn't jive with the rate of the earths curvature at 8 inches per mile squared. Plane trigonometry is used for oceanic navigation. So my question to you is this. Does math lie?
